Charlie Sheen's publicist just quit, and after doing back to back interviews with various media outlets this morning, the troubled actor took a nap and then called in to Pat O'Brien's Loose Cannons show on Fox Sports Radio. Sounds like a busy day!

The Two And A Half Men actor continues to gripe about how show creator Chuck Lorre won't call him back, and he also complains that CBS and Warner Bros. have locked him out and shut down production on his show. Of course, Charlie wasn't ALL negative energy -- the actor commented on the Oscars, noting he would have loved to have made an appearance when James Franco stepped onto the stage in drag and dropped his name. Come to think of it, that would have been a great cameo!
