A man was touring Europe and he was in Spain. He was sitting down to a meal at the local cafe. He noticed that a gentleman was eating something strange but smelled good. He motioned the waiter over and asked what the gentleman was eating. The waiter explained that they were bull's balls from the bull ring nearby.

The very next day the tourist went back to the cafe and ordered the ball dish. When they arrived he noticed that they were smaller than the ones the day before. He motioned the waiter over and asked why the balls in his dish were smaller than the ones the previous day. The waiter replied that sometimes the bull wins.

That joke is about NUTS!
