Cheers stars Ted Danson and Kelsey Grammer look back on their time working on the beloved sitcom and open up about a heated row between them that lingered for almost three decades. The NBC sitcom that focused on a Boston bar and the lives of its staff and regulars ran for eleven seasons from 1982 to 1993. In Cheers, Danson portrayed former pitcher-turned-bartender Sam Malone, while Grammer played one-time love rival and psychiatrist/radio host Frasier Crane, with the latter eventually leading his own spin-off series, Frasier.
