A cocky Northern Department of Agriculture representative stopped at a
farm and talked with an old farmer. He told the farmer, "I need to
inspect your farm." The old farmer said "OK, but don't go in that field
right over yonder."

The Agriculture Representative said, "Mister, I have the authority of
the U. S. Government with me. See this card?  This card means I am
allowed to go WHEREVER I wish on any agricultural land....no questions
asked or answered.  Do you understand?"

The farmer nodded politely and went about his farm chores.  Later, he
heard loud screams and saw the Department of Agriculture Rep running for
the fence and close behind was the farmer's huge-horned prize bull. The
bull was madder than a nest full of hornets. The bull was gaining on the
Rep at every step.

The Old farmer, with a grin, called out, "Show him your card!! Show him
your card!!"
