Comedy Central to roast Charlie Sheen — on same night as Two and a Half Men premiere

To hide their down-there parts, all three actors are holding a poster that says "All will be revealed..." on Sept. 19, the day the new season of Two and a Half Men premieres on CBS. Viewers can look forward to finding out how Kutcher's character will replace Charlie Harper, the alter-ego of fired star Charlie Sheen.

Series creator and executive producer Chuck Lorre has been tight-lipped about how Kutcher will enter the show ever since his addition was announced in May.
