this happened to my cousin last summer on vacation to mexico

my cousin, a big redneck and fan of bullfighting, went to mexico on
vacation. first night there, he enjoyed the matador's successful fight
against an impressively sized bull... after the fight, everyone at the
stadium met at a local cantina to celebrate.

a young mexican chica came out with a large plate with a lid, and sat it
on a table in the middle of the room. when she lifted the lid, my cousin
was extatic to seetwo large montain oysters( for those that dont know,
mountain oysters are bull's testicles, usually found served in the
southern most states).

extatic at the size, and very hungry, my cousin reached for one, only to
be smacked on the hand by the young woman.

"why'd you do that?!!" my cousin asked "these from bull who fought
tonight... very dishonorable to eat them when bullfighter ask for them
first" my cousin asked when he could get some for himself. "tomorrow, we
have another fight, you come back, i reserve for you", said the little
girl.

next night, my cousin was first at the cantina, getting there before the
fight was over. everyone met up, and the girl brought out a plate, same
as last time. she lifted the lid, revealing a smaller plate with a lid.
puzzled, my cousin look up. "wait minute", the girl said. she lifted the
second plate to reveal two small mountain oysters. "is this a joke? why
didnt i get some like those you brought out last night?" my cousin said.
the girl looked at him with a smile and said...

get ready...

"the bull not ALWAYS loose, sen'or!"

Uh, yeeeeee!
