There once was a former Costa Rican footballer who worked in a post office. Unfortunately for his boss, he would only stamp the postmark on the letters once, no matter how unclear it may be. It would infuriate his boss, since some of the letters would be sent back to the post office due to the unclear chop.
One day, his boss decided to do something about. "Paolo!" he barked. "We're getting letters sent back to us almost everyday! Why do you only stamp the postmark once? Why don't you do it again?"
"I'm sorry, boss," came the reply, "but my name is Paolo Wanchope." (one chop)
