 Sumner Sloan abandons his fiancee, Diane Chambers, at the last moment, forcing her to get a job at a bar named "Cheers," and begins an on-again, off-again relationship with the owner, Sam "Mayday" Malone, a former baseball player. However, in the end, she goes to Summer, leaving Sam just like Sumner left her. Sam sells the bar and goes around the world, but upon returning, immediately sets out to buy it back from the new owner, Rebecca Howe. Also working at Cheers are the bartenders, Ernie "Coach" Pantusso and, after his death, small-town Woody Boyd, and headwaitress Carla Tortelli (LeBec). Frequent customers include Norm Peterson, an accountant (who eventually becomes a painter) with a tab the size of a Russian novel; Cliff Claven, an aging single mailman who lives with his mother; Frasier Crane, a psychiatrist and Diane s ex-boyfriend; Lilith Sternin (Crane), an extremely cold psychiatrist who eventually married and divorced Frasier; Robin Colcord, Rebecca s corporat!
