We've all had our fair share of roommate horror stories: bad body odor, weird food habits and/or overly sensitive needs. Last season, the finale of "The Big Bang Theory" left us with a "roommate ... moretransmogrification": Raj replaced Leonard as Sheldon's new roommate and emerged from Leonard's former room with Penny, Leonard's former girlfriend. When the show returns to CBS on Thursday, Sept. 22, we'll see what pans out for the roommates of this endearing nerd herd. Until then, here are more memorable cohabitation situations immortalized on television.
