A Polack walks into the office of a circus and offers to jump to the ground from ten meters up, head first, without a net. The manager does not believe this so they go to the stage. The Polack gets up to about ten meters height, takes a deep breath and jumps head first. He crashes down on his head, lies still for a few moments and then gets up. The manager is fascinated. “That’s incredible!” he exclaims. “I’ll pay you one hundred dollars a night.”
The Polack shakes his head. “Okay, okay, I’ll pay you three hundred dollars a night.” “No,” replies the Polack.
“I’ll pay you a thousand dollars!” says the manager.
“No,” says the Polack, “I’ve changed my mind — I don’t want to jump anymore. I didn’t know it would hurt so much!”
