Третья планета от Солнца

Dick decides to try to win back Mary's heart with a romantic champagne evening, and thinks it a lucky opportunity when the pair of them end up locked in the university library all weekend. Sally, Harry and Tommy, meanwhile, are determined to stop the pair getting back together and head to Mary's house to intervene, where they get distracted and end up running up her Pay-TV bill and hosting a Tupperware party that she'd planned.
