A man walks into a bar. He approaches the bartender and says,
"I bet you $50 that I can lick my eye." The bartender agrees to the bet, so the man takes out his false eye and licks it.
One week later the man comes back into the bar.
He goes to the bartender and says, "I bet you $50 I can bite my ear."
The bartender says, "Your on." So the man takes out his false teeth and bites his ear.
One week later the man comes back to the bar.
He mingles with the other customers for a while and then approaches the bartender.
He says, "You want to earn your $100 back?" The bartender says yes.
"Very well," the man says, "I bet you $100 that I can pee on this counter without getting it wet.
The bartender agrees, so the man pees on the counter, and it gets wet.
The bartender laughs. He says, "sorry about your bad luck."
The man says, "that's okay. I just bet the man down there $500 that I could pee on your counter and make you laugh." ...........
