A guy walks into a bar and straight up to the bartender and says, "I bet you $20 that I can bite my eye".
The bartender thinks about it for a second and says "sure".
The man reaches up and takes out his
glass eye, puts it in his mouth, and bites it. Amused, the bartender hands over the $20.
A few minutes later the man motions to the bartender and says to him, "I bet you $20 I can bite
my other eye
".
Now at this point the bartender is thinking that this guy can't pull the same trick, he is obviously not blind, so he agrees. The man pulls out his set of false teeth, puts them up to his other eye, and bites it. More amused, the barteder hands over the $20.
The man then says "Ok, I
have one more for you. I bet you $100 that you can slide a shot glass down your bar and I'll stand here and piss in it without spilling a single drop!".
The bartender thinks to himself "no way in hell he can do that" and agrees "Ok".
He slides the shot glass down the bar, the man begins pissing. It goes everywhere, all over the bar, the mirror, the seats, you name it - everywhere but the shotglass.
The man hands over the $100. The bartender, wiping down the bar, now smiling over his
victory says "your other two bets were brilliant, why did you make this last one?"
The mans replies, "well I just bet my buddy over $1000 there I could piss all over your bar and you'd clean it up with a smile on your face."
