Best Bar Joke Ever?

A guy walks into a bar and goes up to the bartender, "I want to make a bet with you," the guy says. The bartender says "ok watcha got?" " I bet you $500 that I can bite my right eye." Bartender looks at the man all crazy but agrees to the bet. The guy then takes out his dentures and bites his right eye with it. The bartender is pissed but pays the guy anyways. The guy takes a few shots and then walks back over to the bartender. "I want to make another bet," he says. "I bet you another $500 that I can lick my left eye." The bartender can't even think of a way he can get screwed this time so he agrees to the bet. The guy then takes out his left glass eye and licks it. The bartender is furious but once again he pays the man. The guy takes a few more shots and then stumbles back up to the bartender. "I wanna make one last bet. I don't even think I can do this but I bet you $1500 that I can put a shot glass at one end of your bar and then stand on the other end and piss and make every last drop into that shot glass." the bartender looks at the man suspiciously but decides to take the bet thinking that it's impossible. So the guy puts the shot glass on one end and gets up on the other end of the bar. He unzips and pisses all over the bar. The piss didn't even make it anywhere near the shot glass. So the guy stumbles down and pays the bartender his money. The bartender is so happy that he just made his money back plus some that he starts smiling and grabs a towel and starts cleaning the piss off the bar. The drunk guy then just bursts out in a fit of laughter. The bartender looks at him confused. "why are you laughing you just lost all your money." The guy looks at the bartender and says, " see that guy in the corner over there? I bet that guy $6000 that I can stand on your bar and piss all over it and have you clean it up with a smile."
