The guys at the bar feel bad for always shutting out Diane from their activities and decide to attend anything she chooses... which happens to be an opera.
It's the cozy little bar in Boston where everybody knows your name; welcome to Cheers!
The series was set in the Cheers Bar, and revolved around the life of bar owner Sam, and his employee's. Seasons 1-5 introduced Diane, the snobby, intelligent waitress who is forced to work at Cheers after she is left there by her fiance. Diane also served as the "hard to get" love candy for Sam, the studly bar owner and former Red Sox pitcher. Seasons 1-5 also introduced a variation of supporting characters such as: Norm, the everyday bar regular whose tab is larger than his gut. Cliff, the hard core mailman who was usually the bud of Carla's joke. Carla, the witty and sometimes harsh head waitress at the bar. Fraiser, the sometimes serious psychologist who kept the others in check. And Coach, the lovable co-bartender and Sam's old coach. Sadly, the actor who played Coach died during the filming of the third season. Coach was replaced with Woody, the lovable, naive farm boy. After season 5, Diane dumped Sam and left the bar for good, which led Sam to sell the bar to a big corporation and sail around the world. After Sam returned he was dismayed to see what the corporation had done to it. The new owner was Rebbecca, who served as Sam's new love interest. The remainder of the show revolved around Sam trying to buy back the bar, and win over it's owner.
After Cheer's ended the cast all went their separate way's after 11 seasons. The character "Fraiser" was given his own spin-off, which also lasted 11 seasons.
