Three men go duck hunting one day. Two of them are inundated with stories from the third about his "great" duck hunting abilities. After few hours the first two men have bagged a couple of ducks each, but the braggart hasn't taken a shot.

They question him on this, so he agrees to show his shooting abilities at the next opportunity. A few moments later one lone duck comes flying by. As promised, the braggart stands up and squeezes off one shot. ... The duck keeps flying!

"Gentlemen, you have just witnessed a miracle" says the braggart pointing at the receding duck, "for a dead duck is flying."
