Al and Joe are bungee-jumping one day. Al says to Joe, "You
know, I bet they have no idea what bungee jumping is in
Mexico. I bet we could make a fortune at this down there!"

Joe 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.

On the first day they decide to give a demonstration. So Al
jumps. He bounces at the end of the cord, but when he comes
back up, Joe notices that he has a few cuts and scratches.

Unfortunately, Joe isn't able to catch him, and he falls
again, bounces again and comes back up. This time he is
bruised and bleeding. Al falls again, and comes back up.
This time he's almost unconscious. Luckily Joe catches him.

Joe asks, "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 HECK IS A PINATA?"
