The old gang of Cheers is back in action in its third season. Joining the cast is Kelsey Grammer as psychiatrist Dr. Frasier Crane, brought in by Diane to help Sam recover after he fell off the wagon - without mentioning they're dating. As Diane and Frasier's relationship progresses, Coach gets engaged "Coach In Love, Part 1 & 2". Norm takes off for Bora Bora "Peterson Crusoe" and Sam attempts to sound like Diane in order to impress a female reporter investigating the Boston singles scene "Behind Every Great Man". In "Cheerio" Diane leaves Cheers with Fraiser for Italy, only to frantically call Sam after Frasier proposes in "Rescue Me".
