So if it wasn't enough that Charlie Sheen was in rehab, temporarily putting the kibosh on "Two And A Half Men," it's now being reported that Charlie Sheen might be ditching the show if they don't up his pay raise, which means either canceling the show or renaming it "One And A Half Men."The actor is reportedly asking for $1.5 million to $2 million per episode, and according to PEOPLE, he recently turned down the offer for an eighth season. "He wants to move on," said a friend of the actor. "Leaving is 100 percent his idea."Should Sheen leave, Warner Bros. could lose money as well, Josef Adalian at TheWrap.com notes, especially if its agreement with CBS contains language giving the network an out if a key cast member such as Sheen were to leave.
