An American touring Spain stopped at a local restaurant following a 
day of sightseeing. While sipping his sangria, he noticed a sizzling, 
scrumptious looking platter being served at the next table. Not only 
did it look good, the smell was wonderful. He asked the waiter, "What 
is that you just served?" The waiter replied, " Ah senor, you have 
excellent taste! Those are bulls testicles from the bull fight this 
morning. A delicacy!"

The American, though momentarily daunted, said, "What the hell, 
I'm on vacation! Bring me an order!" The waiter replied, "I am 
so sorry senor. There is only one serving per day because there is 
only one bull fight each morning. If you come early tomorrow and 
place your order, we will be sure to save you this delicacy!"

The next morning, the American returned, placed his order, and 
then that evening he was served the one and only special delicacy 
of the day. After a few bites, and inspecting the contents of his 
platter, he called to the waiter and said... "These are delicious, 
but they are much, much smaller than the ones I saw you serve yesterday!"

The waiter shrugged his shoulders and replied,

"Si senor. Sometimes the bull wins."
