The drunk pulled out his right fake eye and bit it.
After more drinks the drunk said, "I bet you $200 I can bite my left eye." The bartender knew it could not be fake, so he said, "Okay."
The drunk pulled out his dentures and bit his left eye.
The bartender, by now was really mad. After a few more drinks, the drunk said, "I'll bet you $500 that if you slide a shot glass down the bar, I can hop on each stool and pee in it without getting a drop on your bar."
The bartender knew he could not do it so he said okay.
The bartender slid the shot glass as fast as he could. The drunk jumped on stools and peed all over the bar. The bartender jumped up and screamed in joy because he won $500.
In the back he heard, a man yelling in frustration. He asked the man why.
The man replied, "That drunk fool bet me $1000 that he can pee on your bar and you would be happy about it!"
