Al and Frank were Bungee-jumping one day. Al says to Frank, you know, we could make a lot of money running our own Bungee-jumping service in Mexico."

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

This time, he is bruised and bleeding.

Again, Frank misses him. Al falls again and bounces back up. This time he comes back pretty messed up -- he's got a couple of broken bones and is almost unconscious. Luckily, Frank finally catches him this time and
says, "What happened? Was the cord too long?"

Barely able to speak, Al gasps, "No, the Bungee cord was fine...It was
the crowd. What the hell is a piñata?"
