A game warden came upon a duck hunter who had bagged 3 ducks and decided to 'enforce the laws pending.' He stopped the hunter, flashed his badge and said, 'Looks like you've had a pretty good day. Mind if I inspect your kill?'
The hunter shrugged and handed the ducks to the warden. The warden took one of the ducks, inserted his finger into the duck's rectum, pulled it out, sniffed it, and said, 'This here's a Washington state duck. Do you have a Washington state hunting license?'

The hunter pulled out his wallet and calmly showed the warden a Washington state hunting license.

The warden took a second duck, inserted his finger in the bird's rectum, pulled it out, sniffed it, and said, 'This here's an Idaho duck. Do you have an Idaho state hunting license?'

The hunter, a bit put out, produced an Idaho state hunting license. The warden took a third duck, conducted the same finger test, and said, 'This here's an Oregon state duck. Do you have an Oregon state hunting license?'

Once again, only this time more aggravated, the hunter produced the appropriate license.

The warden, a little miffed at having struck out, handed the ducks back to the hunter and said, You've got all of these licenses, just where the heck are you from?'

The hunter dropped his pants, bent over, and said ' You're so smart, YOU tell ME!'
