Once there was a man who walked into a bar and starting talking to the owner of the bar.
He said, “I bet you 300 dollars I can pee into that cup and not a drop out of the cup.”
The bar tender laughed and said, “Okay, sure. 300 dollars.”
So the man said, “Okay one second,” and walked away.
When the man came back he said, “Give me a small cup.” And the owner gave him one.
The man started peeing all over the owners bar and the owner starting laughing.
The owner said, “You didn’t get a drop in, so you owe me 300 dollars.”
The man said, “I’ll go grab your cash. I just bet that guy over there 500 dollars that I could pee all over your bar and you would laugh about it.”
