G-man

A rancher is by his barn, when a car pulls up and a man gets out saying he was going to inspect the rancher land for pot. The rancher asks for ID and the man produces a badge showing he's a Federal agent, The man tells him he's going to cover the whole area for drugs. The rancher says ok but stay out of the back 40, the man again shows his badge and says I'll go wherever I want to go, rancher says don't go in the back 40.
A hour or so later therancher hears screaming and yelling , only to turn around and see the Fed. running with a bull right behind him. The rancher yells to the manm "show him your badge, show him your badge."

Good one
