Who they are: The free-wheeling life of hedonistic jingle writer Charlie Harper (Charlie Sheen) comes to an abrupt halt when his brother Alan (John Cryer) and 10-year-old nephew Jake (Angus T. Jones) move into his beachfront house. The series' premise was revamped in the ninth season, focusing on Alan and Jake moving on with their lives after the death of Charlie, with help from their new roommate, Walden Schmidt (Ashton Kutcher), who is dealing with his own troubles after a bad divorce. What the kids like: Though most of the jokes avoided pandering to younger audiences, the universal humor of watching Jake's adult role models squirm as he asks all sorts of uncomfortable questions about manhood and "the birds and the bees" never gets stale. What parents couldn't get enough of: The fact that Charlie Sheen's booze-soaked, drug-riddled drama behind the scenes was even more interesting to watch than the show itself.
