Sometimes I really question my maturity. · 1:24am Apr 4th, 2013
This. THIS. THIS.
THIS is my Tumblr friend's dog. His name's Harry, which is pretty ironic.
I saw this, and pretty much fell out of my chair and cried laughter.
I cried laughter.
Yeah, I just wasted your time. Sowwy :3
But it was extremely worth it to show you her puppy. Penis. ??!.
- H
p.s. -
Dear Princess Celestia,
Today, I have learned that my maturity level is non-existent. Please don't banish me to the moon.
Sincerely, me
p.p.s. - Anyone wanna attempt to teach me how to php code? Knighty got me curious.
Oh dear God…
I CAN'T STOP
What dog?
Can't stop laughing
All I see is a fuzzy dildo.
Your friend has weird taste.
Maturity is for people that want to stop having fun in life. Rock on, my immature friend.
Contrary to popular belief....
DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD' AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW :3
979260 I LOVE THIS SO MUCH :')
Don't worry. My immaturity is like my virginity. It's something I'll never lose. #foreveralone
Hannah, I can't believe you posted this.
You're so silly sometimes.
Oh my
*Examines Object in picture*
Ma'am, how many times have we told you your dog is not legal in this family environment?
Uhhhh......
We're gonna have to arrest you and throw your dog into the pit of immatureness.
NO!!!! NOPONY TOUCHES MY PENPPY!
*1 hour later*
Well Matthew, this page is now safe.
-FALLS OUT OF CHAIR
ROFLMFAO

Across the world, you're making a lot of boys sad.
I swear, I've seen this before...
979343 She pointed out this is her Tumblr friend's puppy.
That dog has some balls to let itself get its picture taken like that
I guess my maturity is nearly at zero too, cuz I almost died when I first saw that picture
Maturity is not the same as having a questionable sense of humor... I think. And of course I laughed!
Well, I wanted to say something humourous, but everything's taken
979753
Nonsense!
Is that a wiener dog?
979338 Nawww
979311 I scared my own dog... her reaction was priceless
She was standing and then she got scared that I suddenly fell off my chair so she fell down.
979924
Seriously. I think a lot of boys would like to go out with you.
Btw, I still think that's a furry dildo.
You sure that's a puppy dog?
I find this picture rather funny. Thank you for making me laugh today.
Since noone said anything (and probably didn't even read that):
I can, but ah tell ya: CODING. IN. PHP. IS. FUCKING. BORING.
So boring that I, who has read a book about C++ in one night, fell asleep reading the one about PHP.
I've seen that image around the internet for a while, are you sure it is their dog?

980541 It seems interesting, but so tedious!
Figured I might as well learn it for the hell of it.
981516 Yup! Like I said, I got it from my Tumblr friend's page. The post got over 300K notes.

You really flatter me with a heart.
But really, was that a puppy?
984317 haha Whoops! I didn't answer your question because I thought you were being sarcastic!
Yup, it's her actual puppy! Can you not see the head and the hind legs?
984337
Yes... but the shape...

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!!!!
Also, I wasn't sarcastic about it at all.
Somebody will be very lucky if they were able to spend the rest of their life with you.
... Not that I was just flattering you of course. It's the truth.

984418 You're so sweet.
Thanks.(:
984588
I'm not sweet.
I'm Chaotic Note.
983753
Yeah.
If you want to, you have my Skype.
That is quite the interesting image. if I do say so myself.
Gave me quite the chuckle. 
Though I do have to say that has to be the most ridiculous dog I have ever seen.
Well, this is awkward. And my dog's neck fur is too short compared to the fur on his face to look like that, ever. Well, that has to be an awkward position, lying down like that and having it's legs and snout out of plain sight.
