There was a barman who owned a duck that danced on a tin box on the bar. Very entertaining to the patrons.
One day, a guy from the Side Shows visiting town, entered the bar, and was intrigued by the dancing duck. So much so, that he offered the barman $5000, which was readily accepted.
The new owner phoned the barman a day later, and asked "How do I make him stop dancing?.. he kept me awake all last night tappity tap tap on that damn tin box.
The Barman replied "Open the tin and blow out the bloody candles!"
