The Cheers character known for his love of beer and his stool at the end of the bar is Norm Peterson. George Wendt played Norm, who became the show's definitive bar regular.
Norm's entrance usually triggered the famous shout of “Norm!” from the people in the bar. A bartender would ask how he was doing and what he wanted, and Norm would typically answer with a dry joke before ordering a beer. His enormous unpaid tab became another recurring joke, with the finale even suggesting that calculating it would require NASA.
Norm was an accountant, though his career later included house painting, interior decorating, and beer tasting. Despite occasional unemployment, he remained a dependable Cheers customer. His favorite place at the bar and his predictable beer order made him a symbol of comfortable, habitual pub life.
Norm appeared in all 275 episodes of Cheers, which ran from 1982 to 1993. His closest friend at the bar was Cliff Clavin, the mail carrier. Sam Malone was the owner and bartender, while Woody Boyd was another bartender, so neither is the character associated with the recurring “Norm!” greeting and beer ritual.
