Cheers: Grease (1990)

Synopsis
Norm (George Wendt) is beside himself when he learns that his favorite eatery, The Hungry Heifer, is about to close. Galvanized into action, Norm starts circulating petitions to keep the Heifer on all fours. Meanwhile, Sam (Ted Danson) gets his digs in at Rebecca (Kirstie Alley) when her imprisoned millionaire sweetheart Robin Colcord shows up as part of a convict road gang just outside Cheers. Though "Grease" was technically the series' 200th telecast, the producers regarded "Bad Neighbor Sam" (telecast three weeks later) as the official 200th episode. ~ Hal Erickson, All Movie Guide
