A Department of Water representative stopped at the ranch and spoke to the little old rancher.
He told the rancher, "I need to inspect your ranch for your water allocation."
The rancher said, "Okay, but don't go in that field over there."
The water representative haughtily said, "Mister, I have the authority of the Federal Government with me. See this card? This card means I'm allowed to go WHEREVER I WISH on any agricultural land. NO questions, asked or answered. Have I made myself clear? Do you understand?"
The old rancher nodded politely and went about his chores.
Later, the rancher heard loud screams and saw the water rep running for the fence followed closely by the rancher's bull. The bull was gaining on him with every step.
The rep was clearly terrified so the old rancher ran to the fence and shouted, "Your card!! Show him your card!!"
