Omg this is sooooo funny.
Ok well my friend (let's call her Sally. No, it isn't her real name) has a major crush on this guy named David. All she ever talks about is, "David is sooo cute!", "Omg he's looking at me!", and "I love David!" It gets on my nerves 0_o
Anyway, my friend Taylor was all pouty faced because her boyfriend got dissed by a teacher. So me and "Sally" were trying to make her laugh.
Sally: Come on, Sparkle (that's me) we gotta make her laugh!
Me: Okay... I'm a pretty chicken lalala I'm a pretty chicken!!!
(that didn't work)
Sally: David! David! David! David in a bikiiiini (and she did this curvy motion with her hands)
I laughed so hard I cried, my friend Shannon who was sitting next to me squirted milk out her nose because she laughed while she was swallowing, and Taylor said:

Shannon: Okay, I have been MENTALLY SCARRED FOR LIFE!!!!!
Me: Oh my gosh me too!!!
We kept laughing about it the entire lunch time. Then the next day we dared her to go tell David about the whole thing AND SHE DID!!!!!! LOLOLOLOL!!!!!

It was really one of those "you had to be there for it to be super funny" things.
