Samantha Who? (8pm, ABC) - Back-to-back episodes will close out this very funny series tonight. And oh goody, we may get to end with never-to-be-resolved cliffhangers! Samantha is torn between Todd and Winston Funk, and her parents realize that their paths are beginning to diverge (the miserable look on her mom's face when they pulled up in the RV last week was priceless). In other news, Andrea tries to seduce her gay fiance (the second ep takes place at their wedding) and Angie Harmon guest stars as Winston's ex-wife.
