Kelsey Grammer for an argument in which he got angry with him on the set of Cheers, admitting it was “his bad”.The two former co-stars, who played bartender Sam Malone and psychiatrist Frasier Crane respectively on the legendary sitcom, have appeared together on the Where Everybody Knows Your Name podcast, co-hosted by Danson and Woody Harrelson.While reminiscing on their time together while filming the NBC show, they began to talk about their relationship off screen, causing Danson to open up about a particular regret he has.“I feel like I got stuck a little bit with you during the Cheers years,” he told Grammer. “I have a memory of getting angry at you once.”“Yeah, you came and told me that one day,” replied Grammer, without giving away the subject of the dispute.“It’s stuck in both of our memories,” added Danson.
