The Warden said "Hey Sir, what ya huntin?"
The man said "Ducks."

The Warden said "Did ya have any luck?"
He said "Got 3."

The Warden said "Let Me see them." The Warden stuck his finger up the ducks butt, smelled it and said "This duck is from Ohio, do you have a stamp for it?"
The Man gave him the stamp.

The Warden picked up the 2nd duck did the same thing and said "Kentuky duck, got a stamp?"
The man gave him the stamp.

The Warden did the same thing with the last duck and said "Canada duck. Stamp?"
