A team of extraterrestrial investigators awkwardly attempts to pass as an        unassuming American family in this hit NBC sitcom. Try as they might,      Dick (John Lithgow), Sally (Kristen Johnson), Tommy (Joseph Gordon-Levitt),      and Harry (French Stewart) can't quite get the hang of life on Earth. The      second season of the series finds the gang learning about politics, sports,    gender, Christmas, marriage, and more through bumpy bouts of trial and error.  With Jane Curtin. Includes all 26 episodes. USA, 1997-1998, 572 mins.
