2 guys are bungee-jumping one day.

One says to the other, "You know, we could make a lot of money running our own bungee-jumping service in Mexico. They don't have it there."

His friend thinks this is a great idea, so they pool their money and buy everything they'll need; a tower, an elastic cord, insurance, etc. They travel to Mexico and begin to set up on the square.

As they are constructing the tower, a crowd begins to assemble. Slowly, more and more people gather to watch them at work. When they had finished, there was such a crowd they thought it would be a good idea to give a demonstration. So one of them fastens himself to the bungee cord jumps.

He bounces at the end of the cord, but when he comes back up his friend notices that he has a few cuts and scratches. Unfortunately, he isn't able to catch him, and he falls again, bounces and comes back up again.

This time, he is bruised and bleeding. Again his friend misses him, and he falls again then bounces back up.

This time he comes back pretty messed up, he's got a couple of broken bones and is almost unconscious. Luckily, his friend finally catches him and says, "What happened? Was the cord too long?"

Barely able to speak he, "No, the Bungee cord was fine. It was the crowd."

"What's a piñata?"
