Grammer's beloved character, who remained on NBC for 20 unbroken years (including the long-running Frasier), is ushered into the Cheers family when he meets barmaid Diane Chambers (Shelley Long) in a very funny, Emmy-nominated episode suggesting the neurotic course of their future romance. Meanwhile, Sam (Ted Danson), having fallen off the wagon due to his own tempestuous love affair with Diane, has to endure Frasier's questions about how to be intimate with the brainy babe. Elsewhere in Cheers' sardonic community, Cliff (John Ratzenberger), in a sweet but barbed episode, meets a woman (Bernadette Birkett) at a costume party and is afraid of re-introducing himself later. Norm (George Wendt) becomes aware of his mortality and decides to move to Bora Bora, and Sam (in another Emmy-nominated show) has to explain how he got shot in his posterior. Other good things: "The Heart Is a Lonely Snipe Hunter," in which the men of Cheers cruelly initiate Frasier in the manly art of snipe-hunting, and "Bar Bet," starring Jacqueline Bisset as a woman Sam must marry before a certain date or lose the bar forever. --Tom Keogh
