Cheers, the iconic sitcom that ran from 1982 to 1993, featured a beloved cast of characters in a Boston bar. However, the show wasn’t without its behind-the-scenes quirks. Bathroom confusion arose as the men’s and women’s rooms seemed to switch places in some scenes, possibly due to set design oversights. In a blooper from the second season, a visible curtain went unnoticed for multiple episodes. The show also played fast and loose with fire codes, and the Bar Wars rivalry had an odd numbering hiccup with the absence of “Bar Wars IV.” Frasier’s unexpected longevity led to a continuity issue about his father’s death in Cheers, later addressed in the Frasier spinoff. Despite these slip-ups, Cheers pioneered longer story arcs in sitcoms and set a trend with season-ending cliffhangers. Notably, two actresses were pregnant simultaneously during filming, and Coach actor Nicholas Colasanto left a lasting mark by scribbling lines on the set. The mystery of Norm’s wife, Vera, revealed that her voice was provided by George Wendt’s real-life wife, while John Ratzenberger, originally auditioning for Norm, ended up creating the memorable character Cliff.
