200 More Dollars!

A guy goes into a bar and goes up to the bartender. He says "I bet you 200 bucks I can piss in that glass in the corner and not spill a drop." The bartender agreed knowing he could never do it. So the man goes into the corner and pisses all ove everything even the bartender. So he walks back to the laughing bartender and the bartender says "I knew you couldn't do it." The man replies, "You can have your 200 dollars, I just bet those guys over there 2000 dollars that I could piss all over your place and you still would be laughing."
