I must have missed the episode of Cheers where the local police chief attempted to shut it down as a nuisance bar. But it went like this:

Norm gets drunk, passes out and Sam lets him sleep it off in the office. Cliff accidently leaves his mail pouch in a booth comes back for it and Norm, mistaking him for a burglar, blows his head off.

The police chief declares the joint a nuisance bar and attempts to shut it down but the Cheers crew Sam, Diane, Woody, Carla, Frasier and the rest rally to show politicians that Cheers is just a friendly watering hole where a tragedy occurred. Good humor and good judgment prevail. Plus, Sam quietly pays of one of the pols with an autographed baseball from his pitching days with the Red Sox.

Fade Out.
