Laid-back Sam Malone, a former relief pitcher for the Boston Red Sox, owns and runs Cheers, a cozy bar in Boston. He hires smart, uptight -- and jilted -- Diane Chambers as a server, out of sympathy, but their attraction causes constant bickering. Wacky characters fill the bar: sarcastic waitress Carla, beer-loving accountant Norm, know-it-all postman Cliff. When Diane leaves Boston much later, Sam sells the bar, buys a boat and sails the world, but his boat sinks, so he returns. New, ambitious manager Rebecca Howe hires him back, but they love to hate each other too.

Carla and Frasier are dying to know whether Sam proposed to Diane or Janet Eldridge.

Diane has second thoughts about having refused Sam's marriage proposal.

Cliff tries to persuade a wealthy man into marrying his mother.

Frasier is invited to appear on a televised debate featuring several prominent psychiatrists.
