This is a classic I had heard years ago. Thanks to ComedyCentral.com for resurrecting it for me.
A guy is in a bar with a bunch of his friends. After a while of shooting pool and drinking, he whispers something to his friends. A few minutes later he walks over to the bartender and asks for a shot of tequila. After he takes the shot he says to the bartender,I'd like to make a bet with you.
The bartender replies,Sure I'm in a betting mood.So the man bets the bartender $1,000 that he can pee in the shot glass placed all the way across the room and fill it up and not spill a drop. The bartender says,I'll take that bet.
So the man walks to the other side of the room and places the shot glass down. He goes back to the bartender and starts peeing. He doesn't even get a drop in. He pees all over the place; in the bartender's face, all over the barstools and everything.
After he was done peeing, the bartender laughed and said,You owe me $1,000.The man paid the money with a big smile on his face. The bartender asked,How come you're so happy?
The man replied,You see those five guys over there by the pool table? I bet them $300 each that I could piss all over your bar and you'd laugh about it.
