Can they? Probably not. Would they? Heck no.
By now just about everyone assumes that Charlie Sheen has, well let's say, vices. For example, drugs and "escorts." And as long as he remains unchecked he will continue to pursue these vices, which may cause him to continue to get in trouble. But somewhat miraculously he continues to show up on the set of Two and a Half Men on time and delievers his lines well enough for the show to maintain it's No. 1 rating and make CBS millions of dollars.
Well, that is until now. Charlie Sheen has checked into rehab and the hit show has gone on hiatus.
