This American girl is on a tour of Spain and ends up in small town known for bull fighting.   Goes to a nice restaurant and while looking at her menu sees a guy eating a strange looking dish.    She asks the waiter what that guy is eating.     He says it is "bulls balls".     Never having seen it, she asks for one.     The waiter says "sorry madam, we only have one bull fight a day in town, but you can reserve for tomorrow evening".     She says yes and there she is next evening.    The waiter brings in the dish and it looks different from what the girl saw the previous night.     She calls the waiter and asks about it.    The waiter says, "sorry madam, the bull won today".
