Two Americans open a bungee jumping business in Mexico. They set up on the square of a small village.
Bob jumps, bounces at the end of the cord and flies back up by the platform. Jeff isn't able to catch his friend, but he notices that Bob has a few cuts and scratches.
Bob falls again, bounces, and comes back up. This time, he is bruised and bleeding. Again, Jeff misses pulling Bob up.
The third time it happens, Bob comes back pretty messed up -- he's got a couple of broken bones and is almost unconscious. Luckily, Jeff finally catches him and says, "Holy cow, what happened? Was the cord too long?"
"No," says Bob. "The cord was fine, but the birthday party down there thinks I'm a pinata!"
