A familiar face pops up on the February 2nd episode of the popular CBS sitcom "Two and a Half Men." John Carney has a walk on role as a "Cheesy Magician" in the episode titled "David Copperfield Slipped Me a Roofie." According to Mr. Carney, "Don't expect brilliant acting or magic....its just a walk on part, but it was fun to do. They wanted me to be a cheesy magician (quite a stretch for me)....and that's what they got! .... I'm basically doing Mysto, without the makeup!" Here's a show synopsis :: Feeling Alan's underappreciated by his family, Melissa offers him the chance to live with her and her mother.
