Frasier Crane hadn't yet appeared, and the dimwit barman serving drinks and idiotic rapport was still Coach, not Woody. Yet the second season of Cheers is still one of the strongest that the sitcom had to offer, now that the 'sit' had been firmly established, allowing the unparalleled writers to focus on the 'com'.
And they did, using conflict - between Sam (Ted Danson) and Diane (Shelley Long), or barfly bore extraordinaire Cliff (John Ratzenberger) and just about everybody else - to great comedic effect, generating a bombardment of cracking one-liners and note-perfect character moments.
