A redneck was getting in his truck and a trooper pulled up and asked him, if he had a hunting license for this state. The redneck showed him the license, and the trooper was satisfied. But, the trooper saw another duck, and he sniffed its butt and said "This is a Kansas duck, do you have a Kansas hunting license?".
The redneck pulled out his Kansas license, and the trooper was happy. Then he saw a third duck, and sniffed its butt, and said "This is an Arkansas duck. Do you have an Arkansas hunting license?"
Sure enough the redneck pulled out his Arkansas license, and the trooper, said ok. Then he saw a fourth duck, and sniffed its butt and said "This is a Kentucky duck. Do you have a Kentucky Hunting license?" and the redneck pulled out his Kentucky Hunting License.
The trooper couldn't believe the redneck had shot this many ducks from all these different states and said, "Boy, where are you from, exactly?" The redneck pulled down his pants and said "Why don't you just sniff my butt and see!"
