“You’re a magnificent pagan beast!” Upon their first meeting Diane finds out the Sam is a philanderer.
She has been left alone, in Sam’s bar Cheers, by the professor she teaches under as an assistant; he is also her fiancé but his goofy (As Sam puts it) Oxford cloth, aloof from the common man semblance of intelligence makes him and her the butt of jokes in the eyes of the Boston locals who socialize at Sam’s bar. “Oh Sumner”, Diane says, “I’m not beautiful”. “Oh blasphemy” says Sumner, the professor.
Sam’s reply to the “pagan beast” comment is a brief, “Thanks; what’s the message”.Diane doesn’t want Sam to share her private life with anybody else so Sam asks “What would you like me to tell them”, Sam says to appease the other bartender, Coach. He tells Coach that Diane’s a hooker. The character of coach is intellectual study of the buffoon, who waltzes through life being an agreeable, blessed soul. Coach is set as a man who passively agrees with everyone; which is cause enough to believe he did not do too well in the major leagues, acquiescing to the players and his star, Sam who is charmed by the older man’s delicate and beloved touch.
“You were a drunk?” asks Diane. Coach intercedes on Sam’s behalf, “Are you kidding—he was a great drunk!” There is very little exposition; instead the character prologue their lives through dialogue: the meat and potatoes of this show.
The character of Norm, Carla, and Coach reveal how far from home Diane is and they keep her in check throughout the show’s history with her. When she finally does leave, they have left a stamp on her soul, showing that she has seen a little of the charming everyman underbelly of Boston.
Sam tells Diane that she should probably just give up on Sumner and predicts that the professor is going to run off with his ex-wife. When the sense of people, that Sam possesses, comes true, Sam apologizes. Diane asks in a yelp, “How did you know!?” “Bartender’s intuition”, he replies. So Diane is dumped and Sam, pitying her position, offers her a job as a waitress. She finally agrees and is left to discover her limitations.
