I got a fail for you: Trevors birth. JK that's mean.
Yet totally true. LOL
One time my friend had just finished hitting his brand new bong. As he's cradling in it arms, I say to him "Better be careful dude, that thing cost you like 300 bucks."
He says "Dude chill out I got it, this thing isn't breaking anytime soon."
He then proceeds to turn around and smash the bong against a wall.
Fail.
