This made me laugh because, yeah, I could see this happening. I also would probably hear about it on the radio station in Mexicali that I like to listen to "To Help Practice Spanish".
Well, ... or maybe not!
Two Americans decide to open a bungee-jumping business in Mexico.
They set up in the middle of a small village where they gather all the locals to preform a demonstration. 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 he has a few cuts and scratches.
Bob falls again, bounces, and comes back up. This time, he is bruised and bleeding. Again, Jeff misses him. 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 crap, what happened? Was the cord too long?"
Bob looks confused and says, "No, the cord was fine... but what is a piñata?"
