(Laughing hysterically)

There's a small "pub" in Houston called the Mucky Duck, which the proprieters claim is a term for a black swan. There's a carved black swan on a shelf above the bar. It used to sit next to the cash register until one night a (presumably intoxicated) customer grabbed it and ran out the back door with it. Sadly for him, he'd left his credit card with his name on it with the bartender. Probably the most quickly-solved theft case in history.
