This week's Dirty Tricks is hosted by a penguin voiced by Peep Show's David Mitchell, and features more dark magic humour from Scottish duo Barry and Stuart. Pete Firman shocks Coronation Street's Lucy-Jo Hudson with a balloon trick and Penn and Teller impress with their notorious deadly bullet catch trick. All this plus guest appearances from Caprice, Neil Fox and a contortionist who pushes himself through a tennis racket.
