One day while they're bungee jumping, Olaf says to Sven, "You know, we could make a lot of money running our own bungee-jumping service in Mexico." Sven thinks it's a great idea, and so they pool their money and buy everything they'll need: a tower, an elastic cord, insurance, etc.
They traveled to Mexico and begin to set up their equipment on the town square. As they constructed the tower, a crowd began to assemble. Slowly, more and more people gathered to watch them at work.
When the tower was finished, the crowd was so large that Olaf and Sven thought it would be smart to give a demonstration. They climbed the tower together. Olaf strapped Sven into the harness --and Sven jumped.
Sven bounced at the end of the cord, but when he came back up, Olaf noticed he had a few cuts and scratches. Unfortunately, Olaf couldn't grab him before he fell again. When he bounced up a second time, Sven was bruised and bleeding. Again, Olaf failed to catch him. Sven went down again and bounced back up.
By the time Olaf caught him, Sven was nearly unconscious, with a couple of broken bones. Alarmed, Olaf asked, "What happened?!? Was the cord too long?" Barely able to speak, Sven gasped, "No, the bungee cord was fine. It was the crowd. What the hell is a piñata?"
