Man walks into a bar, goes up to the bartender and says...hey man, I bet you $50 I can bite my left eye!
Bartender thinks, man, this guys is nuts, but what the hell. Plops down $50...
Man pulls out his glass eye, bites it, and pops it back in, takes his money and walks out.
Couple days later, guy comes back...says, hey, I'll bet you $100 that I can bite my right eye!
Bartender thinks, man, I know this guy ain't blind, it's a sure win! Plops down $100
Man pulls out his dentures and bites his eye with them...takes the money and walks out.
Couple days later, he comes back in, and tells the bartender, hey, I bet you $250 that if you take a beer glass and sling it down your bar, I can piss in it from one end to the other and not miss a drop!
Bartender thinks, no way, I got this one - plops down $250...and slings a beer glass down the bar...
Man pisses ALL OVER the place. Doesn't even hit the glass...
Bartender is all happy and excited and is hootin' and hollerin'...and picks up his money....then he looks at the man, and see's he's smiling.
He says to the man, why you happy, you just lost 250 bucks!
The man says, because I just bet that table $1000 that I could piss all over your bar and you'd be happy about it.
