This guy walks into a bar and says to the bartender, "I'll bet you $100 that I could bite my left eye."
The bartender replys, "No way man", and slaps $100 down on the bar.
The guy takes out his glass left eye and bites it. He takes the $200 and leaves with the bartender cussing behind him.
Two weeks later the same man comes into the bar, slaps $200 down on the counter and says, "That really wasn't fair the last time. I'll give you a chance to win your money back. I'll bet you $200 I can bite my right eye."
The bartender looks at him and says, "Well you can't have two glass eyes. OK," and puts $200 on the bar. The man takes out his false teeth and bites his right eye. He takes the $400 and leaves with the bartender cussing behind him.
Two weeks later the same man walks into the bar slaps $500 down on the bar and says, "Hey, I'll give you a chance to win all your money back and then some. I'll bet you I can stand on your bar and piss into a shot glass and not even one drop will will splash onto the bar. How about it?"
The bartender looks at him and says, "I know that's impossible." He places $500 down on the bar with a smile and says, "Man is this going to be easy."
The man climbs up on the bar, unzips his pants and proceeds to piss all over his entire bar, the seats, the glassses, everything while hopping up and down.
The bartender is extremely happy and smiles while clapping his hands. When he's done, the bartender says, "Thanks man. That was the easiest money I ever won. You had me a little worried there."
The man replies, "No, thank YOU sir."
The bartender looks at him quizzically and says, "Why are you thanking me?"
The man replies, "See those three men over there cussing and slamming their fists on the table? I bet them $500 each that I could piss all over your bar and you'd be happy about it!
