There are these three guys standind on the roof of a tall building theyre
talking when one of them says:
"Hey, let's see who's dick will go down the building furtherest." so the
second guys says:
"Sure. fine with me." and the third guy says
"just dont laugh, okay?" and the other two promise they wont.
so the first guy lest his dick out and it goes half down the building. the
second guy lets his out and it goes all the way down (yes, these guys must
be martiens or something...) the building. and the last guy lets his dick
out and it goes down the building and across the street.
Suddenly the first and second guy start cracking up and the 3rd guy says:
"you promised you wouldnt laugh" and the two reply "were not laughing at
you, were laughing at the steam roller coing down the street."
