An American tourist in Spain goes to a restaurant and notices another guy eating an unusual dish. He calls the waiter and says, “Excuse me. What is that gentleman eating?”
The waiter says, “Ah, that is our house delicacy—the testicles of a champion bull killed earlier today in the arena. We serve that dish just once a day, but if you like I can reserve tomorrow’s pair for you.”
The tourist considers for a moment and responds “Sure, why not? I like to try new things.”
The next day, the man returns and enjoys the meal. Afterwards he calls to the waiter and remarks “That was delicious, but I don’t understand—why was the dish you served me so much smaller than the one I saw yesterday?”
The waiter responds “I apologize for that, sir. You see, sometimes the bull wins.”
