A cocky 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, "Mr. 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 me?"
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 called out, "Show him your card!! Show him your card!!"
