Rizks went into a restaurant in a Spanish provincial city for dinner, and asked to be served the speciality of the house. When the dish arrived, he asked what kind of meat it contained. "Senor, these are the cojones," the waiter replied. "The what you say?" exclaimed Rizks. "They are the testicles of the bull killed in the ring today," explained the waiter.

Rizks gulped but tasted the dish anyway, and found it delicious. Returning the following evening, he asked for the same dish. After he finished the meal, he commented to the waiter: "Today's cojones are much saltier and smaller than the ones I had yesterday." "True, senor," agreed the waiter. "You see the bull, he does not always lose."
