This is how I heard it...

A guy walks into the bar and says to the bartender, "I bet you a hundred bucks that I can bite myself on my right eye." The bartender thinks about it for a second, and says, "Okay. You've got a bet." So the guy takes his out a glass eye, bites it, and puts it back. The bartender is pretty pissed off about this, but pays him off. About ten minutes later the guy comes back and says, "I bet you a hundred bucks that I can bite myself on the _left_ eye." The bartender thinks, "This guy isn't blind, so he can't have two glass eyes," so he takes the bet. The guy pulls out his false teeth, bites his left eye with them, and walks off a hundred dollars richer. He comes back again about an hour later and says, "I'll bet you three hundred dollars that I can piss in a shot glass from the opposite end of the bar." The bartender, thinking he may come out of this earning some money after all, takes the bet without hesitation. So the guy stands at one end of the bar, whips out his cock, and pisses all over the bar, the customers, and pretty much everything else in range, but doesn't get so much as a drop in the shot glass. The bartender, smiling and laughing about getting his money back, says "Why the hell did you make such a stupid bet? You were two hundred bucks up on me!" And the guy replies, "Because I bet those guys in the back two grand that I could piss all over your bar and have you happy about it!"

KID EGO

I don't recall where I found this file, but I think this is the one you mean:

A guy walks into a bar, goes to the bartender and says, "I'll bet you $1000 I can bite my own eye." "You're on!" says the bartender. The guy pops out his left eye, , and bites it. "It's a glass eye," he explains, collecting the $1000. "How about another bet? I bet you another $1000 I can bite my other eye as well". The bartender thinks and figures that since this guy is not blind, he can't pop out his other eye too, so he agrees. The guy proceeds to pull out his teeth and bite the other eye. "dentures," he says as he collects the money. "How about one last bet? I bet you that I can stand here in the middle of the bar, while you slide a beer glass down the bar, and I'll pee into the glass as it slides down without a single drop hitting outside. $5000 this time". "No one can do that!" the bartender exclaims, and agrees. He grabs a beer mug and slides it down the bar. The guy starts peeing - and hits everything but the glass. The bartender couldn't help but laugh. "That's $5000 you owe me!" "That's all right, " says the guy. "I bet that other guy over there $10,000 I'd piss all over your bar and you'd be laughing about it."
