A Texas rancher was out working when a car pulls up and a man
comes over.

The man says "I'm with the Department of Natural Resources, and
I need to check out your property for allocation of water rights."

The rancher says "Sure, go ahead; just don't go in that field
over there."

The man whips out his wallet and says angrily, "DO YOU KNOW WHAT
THIS CARD MEANS? IT MEANS I HAVE THE FULL POWER OF THE GOVERNMENT AND
I CAN GO WHEREVER I WANT TO, AND THERE'S NOTHING YOU CAN DO ABOUT IT.
GOT IT?"

The rancher politely says ok and lets him go on his way.

A few minutes pass, and the rancher hears an awful screaming
noise. He looks up from his work to see the man running for his life out in the
field with a large bull bearing down on him. The rancher drops his tools
and runs over to the fence and yells,

"Your card! Quick, show him your card!"
