Diane Chambers - Cheers

Diane Chambers, born to her mother Helen (Glynis Johns) and her father who died before Cheers premiered in 1982, is an educated college graduate and a cocktail waitress. In the 1982 series pilot, "Give Me a Ring Sometime", Diane arrives with her then-fiancé Sumner Sloane (Michael McGuire). When he leaves and then never returns, she realizes that she has been jilted and then takes a job waitressing at Cheers. Over time, she develops facial tics occasionally. Also, she uses long-winded, poetic speeches and obscure words that would tire out everyone in the bar and elsewhere, especially in the spin-off Frasier. She attended Bennington College, a private college.

In "Someone Single, Someone Blue" (1983), Diane learns from her mother that she must be married quickly before her father's inheritance will expires. She tries to marry Sam to retrieve her inheritance from her late father, but the mission is unsuccessful, and she loses her inheritance. Nevertheless, the butler Boggs (Duncan Ross) is found to have embezzled her father's wealth, and Boggs and Diane's mother start a relationship, which saves Diane and her mother from poverty.

Carla Tortelli (Rhea Perlman) is Diane's nemesis, and Diane has no one else in the bar to be friends with, especially Sam Malone. Many times she plays morality games with others and wins against them. In "The Boys in the Bar" (1983), Diane is appalled by regular patrons' (i.e. regulars) negativities toward gays, insists that gays are the same as other people, and takes advantage of regulars' perceptions on gays by plotting against regulars. In "The Heart Is the Lonely Snipe Hunter" (1985), Diane scolds men for abandoning her then-boyfriend, Frasier Crane, who has been playing a snipe hunting game for a while, which turns out to be a prank, and she convinces them to find heart into finding him immediately.

In "Cliffie's Big Score" (1986), Diane and Cliff Clavin (John Ratzenberger) are dancing partners for the contest in one night, while Carla is supposed to be his dancing partner. (Carla finds out that Diane was Cliff's first choice and then tells him that Diane has hots for him.) Then Cliff attempts to seduce Diane in the car, but then Diane orders him to "get out" of the car, drives the car, and finally leaves him stranded in the woods.

In "Norm's First Hurrah" (1987), Diane laments how lazy and unambitious Norm Peterson (George Wendt) is over the years and urges Norm to be successful. Then, when Norm attempts an idea for executives, another worker Warren Thompkins (Tegan West) steals his presentation and then becomes scolded by executives for an idea that would hurt the company. Therefore, Norm decides to go against Diane's advice and then to be an average man who can work hard for corporations, even when he may be anonymous to high-rank employees.

Nevertheless, Diane's closest friend of Cheers has been Coach Ernie Pantusso (Nicholas Colasanto) until his death in "Birth, Death, Love, and Rice" (1985).
