Two and a Half Men: The Complete Fourth Season opens with a shock when Alan (Jon Cryer) gets divorced... again. As the season progresses, we watch as Charlie Harper (Charlie Sheen) has a close encounter with his long-deceased dad, Alan attempts online dating and Jake (Angus T. Jones) swaps his Harry Potter posters for the joys of 'hottie' wall art. All the while, Charlie's hip Malibu beach pad is the epicenter for laughs, gorgeous girls, single parenthood, celebrity neighbors and silly escapades. Steven Tyler, Ryan Stiles, Brooke Shields, Morgan Fairchild and many others all make guest appearances and find themselves in the middle of the Harper brood's zany antics.
