A man was visiting Spain and passed by a restaurant in Madrid after a bullfight. They were advertising that they served the balls of the bull who lost the bullfight. Intrigued, the man went inside, only to find that where was a six-week waiting list to get to eat the loser's balls. So he signed up and came back six weeks later. When he got his meal, there were two teeny, teeny balls on his plate. He called the waiter over to complain.
"I've waited six weeks for bull balls. What are these?"

"Sir," the waiter said, "the bull doesn't always lose."
