noise."Mechanic: Insert Clever Title Here · 2:07am Apr 29th, 2023
Yes, I have a clever title for the blog. However, it's a huge spoiler, so you'll get the actual title at the end.
Meanwhile, y'all know the drill:
Source
The vehicle in question is a 2015 Ford F150 XL with a 2.7L turbocharged V6. Came in for the check engine light being on. According to the customer, the light had just come on.
Kinda a less cool one of these
Our youngest tech pulled the engine codes and wrote them down; my manager handed me the list and told me to figure it out. I'll give you the list, then I'll give you some explainers. If you already know your way around engine systems, you can read the list and then skip to the next picture.
P0034 Turbo bypass valve A control circuit low
P0245 Turbo wastegate actuator A low
P0480 Fan 1 control circuit
P0481 Fan 2 control circuit
P0645 AC clutch relay control circuit
P06DB Engine Oil Pressure [EOP] control circuit low
P06DD EOP control circuit performance/stuck off
P2602 Coolant Pump A control circuit low
U0284 Lost communication with active grill shutter modules
P0316 Misfire detected on startup
First two explainers for anyone who's new (or wants a refresher): engine codes are in hex, so you get 0-9 plus A-E as valid digits. "P" codes are Powertrain codes (typically engine, transmission, and transfer case), "U" codes are communication codes (i.e., modules that can't talk to each other or won't respond when called on). Although it doesn't come into play here, there are also "C" codes (chassis) and "B" codes (body). It's possible we'll get more code prefixes going forward; when the standard was written in the 90s, a lot of tech we have now wasn't even imagined.
Okay, now we're going to break down systems. Turbochargers take exhaust gasses and spin a turbine really, really fast in order to force more air into the intake. Engines are designed to accept a certain amount of boost and if they get more than that bad things happen, so there's some kind of blow-off valve to get rid of the extra pressure. Some vehicles also have variable geometry turbines to change how much air they can push at a given RPM. Turbos are part of the exhaust system and intake system of the vehicle.
Cooling fans suck air over the radiator and any other coolers which might be mounted in the front of the engine compartment. Back in Ye Olde Times, they were direct-driven by a belt; when the engine spun, so did they. The faster the engine spun, the faster they spun. Since you don't need them all the time, and spinning around a propeller is a waste of energy when you don't need it, thermostatic fan clutches were invented, and then electric cooling fans. Basically what you might have to blow air around your house. There are often multiple fans, and the computer can turn on however many it needs at one or more speeds. This is part of the cooling system.
The AC clutch is a magnetic clutch for the air conditioning compressor. When the engine is running, the AC pulley is always turning; when the clutch is engaged, it links the compressor drive to the spinning pulley, and you have air conditioning. This is part of the air conditioning system.
The EOP control circuit runs the oil pressure. Once again, in Ye Olde Times, there was a mechanical pump and the faster the engine turned, the more oil pressure you had. (There was a mechanical bypass so it couldn't get too high, sort of like the turbo blowoff.) A lot of cars these days require oil for more things than lubrication and cooling, so they have two-stage oil pumps in order to get the pressure and volume you require at low RPMs. This is part of the lubrication system.
The coolant pump pumps coolant. While most vehicles still use a mechanically-driven coolant pump (either driven by the accessory belt or by the timing belt/chain), many of them have electrical booster pumps for various purposes. For reasons which will become obvious later on, I didn't investigate this system at all, so I don't know the specifics. It's part of the cooling system.
The active grille shutters are shutters over the radiator and some of the other coolers in the front of the engine compartment. They can close to block off airflow, or open to let it through; on this vehicle there is an upper and a lower set which I believe can be operate separately. I don't know all the specifics of their operation or whether their main function is aerodynamic or to let the engine heat up faster/more tightly regulate its temperature when it's running. They're a part of the cooling system.
Finally, we have the 'misfire detected on startup.' As far as I know, that's a code unique to Ford, and it means in the first few thousand revolutions, one or more cylinders didn't fire. That code was not diagnosed, and we can ignore it for the purposes of this blog—several of the other problems could have caused this code to set.
Following along so far?
As a mechanic, we hear far too often 'it just started making noise,' and we find out that not only are the brake pads worn out, the friction material is gone. So is the pad backing, and it's the caliper pistons that are trying to stop the vehicle now. And the brake rotor? Well, it's been worn through to the cooling fins; what was a dual plate rotor is now a single plate rotor. I dunno if they think it's going to be cheaper if they claim the noise just started or if they don't want to admit they've ignored the problem longer than they should have (I'm sure this isn't unique to mechanics; I'm sure every professional sees this). In the case of the check engine light . . . well, some vehicles tell us how long it's been on, either in terms of ignition cycles or mileage, so be careful if you're lying—your PCM might have the receipts.
I'm used to customers lying to us, and this code list certainly gives me a raised eyebrow of skepticismTM. There are a lot of systems involved which don't have much in common except that they're all in the engine compartment. Something in the lubrication system and in the turbos failed at the same time as the cooling fans and the grille shutters failed and also the AC compressor for good measure? Off the top of my head I can't think of anything that all those components would have in common; besides being part of several different systems on the powertrain, they're scattered all around the engine compartment.
Armed with a list of codes, I waded into Identifix, just to determine what a quick test would be for each system; maybe I could refine my testing somewhat. A lot of times with multiple failures, figuring out what all the systems have in common (if anything) can help narrow the diagnosis. For example, there are two fan codes; maybe they share a thing that might fail and render them both inoperable.
I could also potentially find something that's shared in a system that still works and rule that out. For example, just today I was quick-diagnosing an inoperative horn on a 2013 Town and Country. I won't go into all the details, but I determined that the horn did work when the alarm was set, which means from the relay on the horn circuit is good. Pushing the horn pad on the steering wheel doesn't work, but according to the wiring diagram, that's multiplexed through a LIN bus along with the cruise control buttons and the radio buttons (on the steering wheel); since those buttons worked, I know the LIN bus is good, the clockspring is good, which only leaves a few components that need to be tested if the customer authorizes it (they didn't).
I don't remember which combo of codes broke the case. Identifix has a semi-smart search, and when I typed in one code it gave me two others I also had, two other codes which didn't seem related. For example:
P0245 Turbo wastegate actuator A low, P0645 AC clutch relay control circuit, P06DD EOP control circuit performance/stuck off—check fuse 97.
That's an odd combo of things to be powered by the same fuse, and that got me to thinking. If fuse 97 powers those things, what else does it power, directly or indirectly?
I'm not going to beat around the bush. Fuse 97 is doing some heavy lifting; fuse 97 powers all the things. I got a power distribution diagram, and. . .
The diagram shows that it powers the AC clutch relay, Cooling fan relays 1-3, both grille shutters, the turbocharger bypass valve, the turbocharger wastegate regulating valve, the oil pressure control solenoid, and the cabin heater coolant pump. Everything that's set a code (and a couple of things which haven't yet). I don't know yet that it is the fuse that's blown, but now I have my common cause, and if the fuse is good I can test at the most upstream connector or splice (in the wiring diagram that would be splice 114, and there are no connectors).
The customer wasn't lying, when the fuse blew, the check engine light would have just come on and it would have set this many seemingly unrelated codes.
I once had a rookie believing that you could tell if a fuse was bad by licking it.
The more conventional way on automotive fuses is to look through them; they're made of translucent plastic, color-coded by their rating (for the traditional types [mini, maxi, mega]; J-case and others have a clear viewing window and a color-coded body) and there's a little swirl of wire; if it's broken or if there are burn marks, it's probably bad. You can also use an ohmmeter on the contacts if you're feeling fancy.
This fuse was blown. I put a new one in, and all the things I could easily test worked as intended (I could turn on the cooling fans and run the active grille shutters), and when I did a self-test none of the codes came back. I know why it set all the codes it did, but. . . .
I don't know why the fuse blew, and if I want to know why the fuse blew I have to test every one of those systems.
My manager called the customer, and he said that he'd just had something in the front end fixed at the body shop, which implies damage and the working theory that the grille shutters got jammed and that's what blew the fuse. We gave the vehicle back to the customer, told him to see what happens . . . so far the check engine light hasn't come back on.
And thus we have . . . The Mystery of Fuse 97.

Wow…that’s a lot of components to run through a single fuse. Doesn’t seem like a good idea since it disabled so many systems.
I really enjoyed you going through your diagnosis and analysis. I’ve always liked trouble shooting and learning how to perform it better. And your stories are always interesting and fun, too!
The fuse only powered t oil pressure sensors, not the oil pressure pump? as my first thought was someone pulled a plug or remoduled something, but then, Im in no way a mechanic, I just complain that if Im using a computer plugged into the OBD, why hasnt the company got the langage translation base file available so first you do a code to human translation, but then can apply a human general to human local language translation also?
How much would car companies complain if it was govt mandated that All codes created have to be defined, and declared to Library of Congress archives for free access and any codes found not declared classed as tax avoidance or which ever is the nastiest unlimited fines through danger to publeic and govt revenue stream?
Or they could just go for simpler serial hybrids where because the engine has far fewer operational states, it dont need such complex controllers?
A curious little story, do more! You structured it well enough to follow along and feel that you actually learned something new in the end
Wait...is that...is that a...MOTH pony?!
Oh dear LORD just when you think they can't GET any cuter!!
Poor rookie, I don't see how licking a fuse would tell you anything unless it was live, in which case a 10A fuse sounds ugly. Pretty neat trouble shooting run down though, sounds like it saved you a lot of time and the customer some money. Its always great to hear about a professional good at their work.
No one tells obvious lies to professionals for stupid reasons, doing something stupid is always a good enough reason. My car came from the dealer as a convertible I swear.
*If the IRS thinks you owe them money they will hunt you down. If you don't file taxes and never hear from them they probably owe you money.
And I think I’m cool for being able to get my mess of Skyrim mods working. I’m always surprised what leaps and hurdles you have to go through to get cars fixed. Like, I have the patience to find obscure forum posts on why a program isn’t working or to find the hidden setting in Finale that actually allows me to adjust staff space. But I’m not sure if I can stomach what you do.
Said it before, I'll say it again.
This Baby Boomer had a number of roommates back in the 1970s who were backyard mechanics. Based on what I remember them doing to cars (mostly on the kitchen table), you are a LOT more computer tech than what they would have called a mechanic.
Hell, you used to be able to open the hood from outside the car. Nobody'd even heard of a dash lock. You were worried about somebody stealing, say, the battery then you had to install a padlock.
One of the reasons cars cost so much more is that they've got a LOT more parts.
5725426
You don't think customers will make your job harder by telling you stupid lies?
All I can say about that is "Dude, you can't possibly have ever worked retail.".
5725418
And I just realized that must be what a flutter pony is!
As an internet service tech, the usual lie I hear is that it never worked/the problem has been going on for a lot longer than it actually has.
Which is kind of the opposite lie to what you usually get.

Yikes, that could have been a pain. At least you didn't find a creative Fuse replacement...
Speaking of pains, remember that CaseIH Magnum 340?
Yay new old problems. The high range clutch pack went out, limiting its top speed to 8.5 mph. It was replaced a year ago... and the fix will cost $30,000. And involve the machine being unavailable for an extended period.
So... the tractor is going to be replaced. And I will be talking with the dealership service lead about how to prevent those bolts from being loosened on the new machine, etc.
Thank Celestia Fuse 97 didn't run the flux capacitor and the Mr. Fusion™! You might've got stuck in 1955! Can you imagine if the hover-conversion ran on that thing, too?! Great Scott!
5725415
Has done more.
Will probably do more in future too.
Check back catalog of blog.
They are all good.
5725440
I remember my dad showing me how to start his truck by opening the hood (from the outside, as you said) and then shorting the battery to... possibly the ignition coil (it was a lot of years ago).
Cars used to be simpler; there's a reason that now they're not.
5725406
There are some very specific codes that we don't see very often; one that I think I documented in a blog post a while back was "Key was programmed incorrectly." (That one was set when my manager reprogrammed the keys on a Lincoln without reading the instructions; there's a very specific way they want you to do it.) And a couple others that have one-step diagnosis, usually 'internal failure' codes in modules. Usually you clear the code and if it comes back, replace the affected module.
5725407
A lotta fuses run many things, not always seemingly related . . . that's just how they do it.
Incidentally, aside from the check engine light, the vehicle seemed to operate normally (although the AC probably wouldn't come on), so apparently it's programmed to work around all these things failing simultaneously.
Thanks! I aim to entertain and educate
5725408
In the US, at least, there is a structure to the codes that must remain the same no matter who makes the car--a P0300 is going to be a misfire regardless of the make, a P0420 is going to be a catalyst failure, and a P07xx code will always be for the transmission. Some manufacturer-specific codes won't be supported by a cheap code reader, but a good scan tool can get at least the code number, if not a description.
I don't know how it's working with startup electric car companies; they might be able to skirt the rules since the law (as written) only specifically applies to codes which effect emissions and nothing that goes wrong on an electric car effects emissions. I would imagine any legacy automaker would use the same codebase and connectors as everything else, though, to keep it simpler on their end.
Some of those might be more complex, I don't know. Managing charging and batteries and such is more electronic than mechanical, whereas a lot of stuff on traditional drivetrains is a computer commanding a mechanical thing.
Maybe if we're slow some day, I'll see what kind of documentation/service information we have for some of the new EVs, or even some of the older ones, like a Nissan Leaf.
5725415
Thank you! I have a fair number of mechanic blogs which--hopefully--educate and entertain. Or if not, at least you get some cute pony pictures
5725418
It sure is!
I know, right?

It's only 12vDC, so it's not too spicy.
I'll be honest, it's as much having good resources and knowing how to use them. I could have spent a lot more time troubleshooting it if I didn't get that helpful shortcut on Identifix.
In my scheduled to be next blog post, I spent a lot of time and replaced a couple parts I didn't have to because I didn't check Identifix first. . . .
We do keep a customer-first mindest at our shop, and often don't charge for little stuff, especially if it's a regular customer.
You'd be surprised how many people lie, and there's no point to it. Tell me what you did; it'll save you money and save me time.
*If the IRS thinks you owe them money they will hunt you down. If you don't file taxes and never hear from them they probably owe you money
We'll find out if that's true
5725428
Honestly, a lot of the time it's getting the documentation that's the challenge. I've got pretty decent google-fu, and enough understanding of automotive problems that if I can't find what I'm looking for directly, I can often keyword myself really close . . . not that long ago I was looking for documentation of a specific code, and there was none, but there was a similar code that would set for a slightly different problem with the same system and that got me results.
There's also a fair bit of vehicle familiarity that helps . . . knowing that this is the way a particular automaker usually does things. It's why I struggle with German cars, 'cause they do things a very different way than American and Asian automakers. I'm sure to a Mercedes or VW tech, though, it all makes sense.
5725440
Oh yeah, totally. I would say that most of our diagnosis these days is electronic . . . I use my voltmeter a lot more than I use my vacuum gauge.
Still got a truck that's like that
The good news is Ford brought that feature back on the Transit Connect. The hood release is under the emblem on the grille. You fold it up like you did the trunk badges back in the day, and there's a keylock underneath.
They do, and customers have higher standards. I've often wished that we could get a base-model Vega or Pinto as a loaner for people who are complaining about how complicated cars are nowadays. See how they like its lack of features.
I have a S-10 that's so base-model, it doesn't even have a cigarette lighter . . . that was apparently an extra-cost option. It also doesn't have a dome light or a headliner. Probably one of the last years for a true base-model truck: manual brakes, manual steering, manual transmission, zero options. It might have even come from the factory with a radio delete, although it had one installed when I got it.
5725444
I think that the flutterponies in canon are more butterfly-based than moth-based. Although really, it's not that much of a stretch to say a moth is just a nocturnal butterfly.
5725445
The dealer gets the 'it never worked' complaints, usually
Hard to convince me that the engine never worked when the car's got 100k on the odometer. So yeah, it's usually the 'it just started making noise' or 'the light just came on.'
I do have a legit 'it never worked' computer; bought a refurb Dell off Amazon for a couple hundred dollars, and it mostly managed to finish setting up Windows before it decided to not. If I ever get frisky, I'll pull the case off and see if there's anything inside I can use.
Since then, I've only bought from brick-and-mortar stores where I don't have to mess around trying to mail back a defective unit, I can just drop it on their counter and tell them it's broken and I want a new one . . . like my last HP which may or may not have mostly worked--there was no way of knowing since it wouldn't drive a monitor.
5725446
I know, right?
I'm sure there's at least one part on the car that does the opposite of what you'd think it does, I just can't think of what at the moment.
The closest I can think of at the moment was GM's insistence at calling their alternator a 'generator.' Which it wasn't, it produced AC and then rectified it to DC by means of a FULL BRIDGE RECTIFIER. (language and electricity warning)
5725449
Not on that one. I've found semi-creative fuse replacements before (oh, the ten amp keeps blowing? Let's put in a 30 amp, that should work).
Yikes! You could buy ten of my minivans for that.
. . . . how many Dodge Caravans would it take to pull farm equipment across a field? They're open in back (if you take the seats out) so you could put a motor driving a PTO inside the rear of the last one in line.
Man, that's something where I would say maybe welding the bolts to the case with a couple of tack welds might be a good solution, especially if they're ones you rarely (or ideally never) need to remove.
5725508
I know, right?
Imagine what they'd think if that truck dropped in 1955. It's got a full-color touch-screen in it, as well as animated splash screens on the instrument cluster.
5726035
You think THAT'S basic? You ever see a 1950s VW Bug?
They ran the windshield wipers off the compressed air in the spare tire. (Rear engine, it was in the front trunk.) This guaranteed that the tire was flat & wipers would fail quickly
They also didn't have a gas gage. The kludge to fix that was to put something in the gas tank too big to go down the fuel line (large marbles, say). You hear them rattle, it's time to fill up the gas tank.
5726039
Regarding welding the bolts to the case, not an option for my skill. The case is cast material, and unless done just right, the welds tend to tear away from it. I've welded studs to cast wheel hubs before, and often enough I have to re-do it a couple times before the nuts can be torqued down right.
To clarify, the massive price tag is for the disassembly of the tractor to replace two of the three clutch packs (medium and high ranges).
The reason the boss has traded it in on a replacement (same model, some different options, lower hours) is that the farm can't have this piece of equipment not work right during use. It's already put a delay on getting ready for spring planting. However, the primary use is to put a bulldozer blade on it and push feed up on a pile and pack it down (bunker silo; the top is then covered with a sheet of plastic and tires to hold the plastic down). We don't have any other equipment that can do that task. We're dealing with some of the effects of other equipment breakdown and delays from about seven months ago in the quality of feed for the farm's cows.
Farming requires an interesting multi-perspective on time: there's right now, today, this week, this month, this year, this decade. Juggling the needs to clean a barn, with what fields are available, what crops are or will be on the fields, what nutrient levels are in those fields' soil... and that meshes with animal needs and health, employee needs and capabilities, equipment and availability, regulations, neighbor opinions (the joys of edging other peoples' lawns with 25' wide equipment!)...
Thus, a decision was made to make payments on something that you could buy a small house in the country for.
5726042
Heh! I deal with untrustworthy fuel gauges all the time. If I'm lucky, I can open the tank and dip a stick in to see the level of the fuel.
Oh, and something that just came up the last couple days, regarding fuses.
Coworker: I left the bad relay out, I'm not sure what it does and the skidloader runs anyway.
Me, two days later: Hm, battery not charging light is on. *rummages in spare parts bin, sticks generic automotive relay into socket, battery not charging light goes out*
Guy does good work a lot of the time, but... some days, I tell ya.
This is a bit off topic, but ¿how is the training for electrical cars proceed? We do not want the admiral of your fleet to loose his job.
5726030
A...FUZZY pony! ...hnnng... (thump!)
5725408
So I did check up on a Nissan Leaf, and we do have some service information on it, including codes documentation and maybe diagnosis (I didn't have time to look deep into it). Pages of wiring diagrams as well.
5726042
Oh yeah, there's lots of older stuff that's way more basic, it's just kind of surprising to have a late 80s truck with computer-controlled engine management that's still so lacking in conveniences.
I was less surprised at my late 70s base model farm truck being really stripped down (it also had virtually no options, although it did come with a cigarette lighter)
5726080
Just today I had a vehicle with a battery draw due to a bad relay (it was hot to the touch, and when I pulled it out the battery draw went away). However, rather than just say that I'd fixed it, I consulted the wiring diagram and figured out which relay it was and whether the car needed it or not.
Turns out not--it was the horn relay, and the horn already doesn't work in that car (nor would it if the relay were replaced).
5726078
I would think that even a sloppy weld would keep the bolt from turning, or make it obvious it had if the weld broke. Maybe if the bolts are somewhere where you can see, little flags like they put on semi-truck lug nuts sometimes? Or else (if they're visible) you could put a vertical or horizontal line on every one of them with a paint marker, and if any of them have turned, you know you have a problem while it's early enough to address it.
I kinda figured that was a lot of it. As I'm sure you well know, there's always those fun extremes where it's a ton of labor to replace a cheap part, or a really expensive part that's easy to change.
That's the joy of certain kinds of equipment . . . we don't have anything in the shop that has to work or else we can't do anything except electricity, although there's a lot of equipment we have that relies on the air compressor operating.
Yeah, it's a different kind of thinking, that's for sure. I generally don't have to think very far ahead in much of anything, which is nice.
That does remind me, I've been meaning to write a fic or mention in a fic how earth pony absenteeism at school is ignored when farm things come up--like when it's harvest time on a particular farm, those foals just don't go to school, and Cheerilee gets it. Or else businesses being closed during haying season 'cause everypony's helping with it . . . ponies at least have an advantage since they can control the weather.
Maybe Apple Bloom or one of the other farm foals coming into class late covered in manure or something . . . dealing with calving time or lambing time. . . .
I bet it costs more than my small house in the country did
Also, I knew about bunker silos, 'cause I live in farm country, but I didn't know what they were called.
5726136
The good news for us, at least for now, is there aren't enough electric cars in our market area to affect us. I expect that'll slowly change over time, but it'll be a while--even if all the automakers stopped selling internal combustion powered cars starting in 2024, it'd be a while before that trickled down to us.
Our owner does try and keep us on the edge of the curve in aftermarket repairs; we just recently attended a class about driver assistance features (lane-keep, adaptive cruise control, blind spot monitoring, etc.); we're also the only local shop that can program onboard computers on most domestic vehicles, and just last year we got a brand new 1234-yf machine for modern air conditioning systems.
5726213
I know, right?
5726465
That would be a delight to read! It is also why the US school system has such a long summer break-- historically, a LOT of kids wouldn't have attended anyway.
I have apologized to a bank teller for my rather odoriferous attire. There's also a sign at a local doctor's office requesting people to not wear their barn boots.
5726467
These new systems, especially autobreaking, increase safety, if drivers use them responsibly:
We have idiots using lane-keeping for autonomous driving —— ¡the technology is not here yet!
I figure that by 2030, autonomous vehicles will drive better than the stupid monkeys, but it is not 2030 yet.
5726472
Yeah, and there are of course other days depending on where you are (my rural high school had very high absenteeism on opening day of deer season; a different suburban school I attended were missing a lot of kids on certain Jewish holidays)
Those are the kinds of things you have to get used to in the country. It's really a groove I can put a story in, since I've lived in both wealthy suburbs and the country, and I've heard lots of suburbanites' reaction to being in the country.
Ferinstance, I was driving some of my city friends around out where I used to live, and just cruised through a stop sign. They pointed it out, and I said that the corn was down, so I could see nobody was coming. . . . It's probably changed since I lived there, but there used to be a four-way intersection on a pair of rural roads that didn't have stop signs on any quadrant. I assume that the township figured if two cars crashed there, they were both at fault.
5726478
Yeah, a lot of the features are really beneficial. Autobraking can't prevent all accidents, but it can reduce the severity of most of them, for example (the NTSB covered a case where the accident probably still would have happened if the autobraking on the truck had been enabled, but it would have been less severe and probably non-fatal). ABS and stability control usually work well, blind-spot monitors are great, as are backup cameras. Some cars now have side-view and front-view as well.
I don't think they will, or that they only will on certain roads. Even the simple systems have trouble on some of the roads where I live--for example, lane-keep assist doesn't work if there aren't lane markings on the road.
Different weather conditions can also cause problems, such as snow cover. I know on a familiar road where I need to drive, and I can also get feedback on some roads from centerline and fogline rumble strips (they're spaced differently, so you can tell which one you've hit); AFAIK no driver assist system can use that.
5727601
Yeah, auto braking is great. It has shown its worth and should be on by default. BlindSpotMonitoring and BackUpCameras are great too.
¿ Have you seen how much smarter GPT4 is than ChatGPT (GPT3)? By 2030, the autonomous vehicles could be safer than monkey-operated vehicles in all circumstances and conditions, assuming that CelestAI does not upload us all into virtual ponies in EquestriaOnLine:

Hasbro just released the official My Little Pony MMO, with an A.I.

Never underestimate the moronic monkeys.
