Do you guys see this? Or is it just me? · 5:45am Jan 23rd, 2013
C-can you guys see that dark thing at the bottom of the stairs? Or is it just me? I had to squint for a couple seconds before I saw what it was.
Please tell me it isn't just me.
Did you shit bricks like I did the first time I saw that? My friend showed it to me in a dark room and I swear I screamed bloody murder. I shat shit.
..........................
You should've seen the looks on your faces. 
Haha wait no come back please love meeeeeeeeeeee don't you dare click that unfollow butto- well shit.
Oh screw you. I zoomed in and everything!
WHY WOULD YOU DO THIS?
Damn. The trick didn't work. 'It' appeared as I was shifting mah chair for a better look
Again, I'm a sucker for these
It's rapin' time.
Well, you sure got me.
742151 742154 Noooooo I'm sorry.
I just wanted to see if you guys fell for it too. When my friend showed it to me, I swear, I screamed foul words like F&%^. I hope the neighbors didn't hear me. >.>
Nope. not gonna look.
Mother! Ahh! I felt my bowels tighten. God that was a good one! Respect!
742160 Oh, well, I just gasped.
T_T Please don't make me
742160
Aww, don't worry.
You have a way with words.
Anyway, you got me pretty good.
Well played, Hannah.
You made me fall out of my chair.
742160fortunately I was eating chocolate at the time but still dang that's great. I wish I could post this everywhere because really, that was awesome.
742155 DAMN IT DAEMON YOU RUINED IT WHYYY
742157 742159 Wasn't just you guys.
Haha, I felt a shock wave run up and down my arms and I banged my knee on my desk. Trying to escape. From whatever that was.
742163 REG DON'T MAKE ME BEG. Although the surprise was probably spoiled.
742164 Aha! Up top! (\
742174
Ah! Does it hurt?
742165 Better than what I did!
742166 Lol, I won't. But it was pretty funny to see others' reactions.
It's not that scary, honestly. Just surprising. And funny once you realize it's over.
742168 Bwahaha thanks! >:D I live for these moments. I just honestly felt like giving a good prank to my Followers.
I think I succeeded, no? Anyways, it hurts a little. 
I have a bruise on my knee now.
742171 Heh, sorry!
I was feeling quite angsty, so I decided to pull a joke off! I won't do it again. ...most likely.
742172 Haha, thanks! I can't believe I actually pulled it off!
Oh you.
742195
Awww.
Here, let me heal you with my nuzzling!

742196 Oh me.
One of my lesser concealed pranks, but I just did it to cheer myself up. The flu's been a doozy.

Not if Twilight nuzzles you first!
742195i don't want to hate you for it so instead I'll just send the image to all my friends if its okay with you
742204

742206 Awww noooooo, don't hate me.
Your name is NaughtSought after all. Hah.
And yeah, go ahead! I actually found this on my friend's Tumblr and decided to share it with you guys here. So knock yourself out! Tell me their reactions when they let you know!
742208 megusta.jpg
742209dont understand what my name has to deal with that but I can't hate anyone. Even those who have tried to kill me I can't hate.
Also here goes. Let's hope my friends are forgiving.
742217 Eh, your name just reminded me of the Mischief Managed thing in the Harry Potter series.
742221 still font get what that has to deal with anything and now I question how your brain works. Put a smile on my face though at that.
I fucking knew it, I've got Pinkie Sense sucker!!
My computer is laggy it was in slow motion
742226 Gotcha!
Not my best prank, but worth a shot.
742227 DAMN IT NOOOOO. That just ruined the fucking surprise.
It's okay. There'll be plenty more where that came from. bwahaha 
742231
At least it wasn't an .SWF with a scream-track
742239 Huh. I could do that.
Just kidding. If my friend pulled that one on me, I'd be pretty pissed. Especially late at night. Like right now. When I scared myself shitless with that gif. Right before bed. I'm so smart.
742221 Love that series
and that map
742241
And I'm a headphone user when I'm at my computer.
Boy, I'd beat your ass till it was blue
742244 Thank you! At least someone got my reference!
HARRY POTTER IS BEST MARAUDER! 
742245 Heh, if you can reach it. It's just out of sight.
Wait. What am I doing.
wat. waaaaaaaaat.
Lol at least I know you use headphones. Advantage taking skills, deploy!
742247 Did you solemnly swear that you were up to no good

Meh... still not as scary as
Stairway SimulatorSCP 087.(Yes, I know that the face at the end was just cropped out.)
Up your ass with broken glass.
742252 Of course I did! It's a ritual!
742255 You're such a good friend. What would I do without you~
742262 Yeah, I knew that. What creeped me out at first was I thought it was some kind of weird CGI where an out of proportion woman was crawling up the stairs (plus, I watched a horror movie like that a few days ago, "Mama", which scared the living hell out of me). So...
742331 You're too kind. Yours too!
Just kidding. I take it you were shocked?
742347 Nah, that was just for all the people who actually DO get scared by it.
742352 Haha okay.
Oh gosh, must stop watching this .gif before going to bed. I'm just gonna log off now.
742262
SCP-173 is scarier
I DIDN'T LOOK! YOU CANT MAKE A DICK TWIST ITS OWN TITTY WITHOUT THE CUSTARD! And you forgot the custard!

742609
