The most successful Cheers spin-off was Frasier, which featured Frasier Crane following his relocation back to Seattle, Washington. Sam, Diane, and Woody all individually appeared in Frasier episodes, with Lilith appearing as a guest on multiple episodes. In the season nine episode "Cheerful Goodbyes", Frasier returns to Boston and meets up with the Cheers gang, later attending Cliff's retirement party.[citation needed]
