It looks like we've finally learned how much CBS was willing to put up with Charlie Sheen. CBS announced Thursday they were suspending production on his hit sitcom Two and a Half Men after Sheen called into a radio show and ranted against the show’s producer. Sheen called show creator Chuck Lorre a “clown” and (inexplicably) repeatedly used Lorre’s Jewish birth name, Chaim Levine. Sheen responded to the suspension with an open letter to Lorre, calling him a "little maggot" and saying he wishes the executive producer "nothing but pain in his travels." Meanwhile, Sheen’s ex-wife Brooke Mueller has moved back in with him, Mueller’s mother said Thursday, bringing the couple’s almost-2-year-old boys with her.
