Cheers, the iconic sitcom running from 1982 to 1993, featured beloved characters in a Boston bar. Behind the scenes, there were quirks like bathroom confusion and a visible curtain blooper. The show played fast and loose with fire codes, and the Bar Wars rivalry had an odd numbering hiccup. Frasier’s longevity caused a continuity issue addressed in the spinoff. Cheers pioneered longer story arcs and season-ending cliffhangers. Two actresses were pregnant simultaneously, and Nicholas Colasanto left his mark by scribbling lines on the set. Norm’s wife, Vera, had her voice provided by George Wendt’s real-life wife, and John Ratzenberger, initially auditioning for Norm, created the memorable character Cliff.
