Reminds me of this one: A guy went to a bullfight in Mexico. After it was over, he went to a restaurant and asked the waiter what was good on the menu. "Bull fries, señor, make you strong like Popeye!" The tourist wasn't convinced, but the waiter explained to him that when the bull lost the match, he was relieved of his bullhood and it was served at the restaurant. He ordered and out came a piping hot plate with two huge pieces of meat. Sure enough, it made him strong like Popeye. For the next several days he ordered the same thing. A few days later he came back and ordered. On the plate were two scrawny pieces of meat. When he asked for an explanation about the change, the waiter replied, "ah, señor, the bull does not always lose!"
