In the 11th-season episode of Frasier, "Caught in the Act," Frasier's married ex-wife, children's entertainer Nanny G, comes to town and invites him backstage for a rendezvous. Nanny G appeared on the Cheers episode "One Hugs, The Other Doesn't" (1992) and was portrayed by Emma Thompson. In this episode of Frasier, she is portrayed by Laurie Metcalf. A younger version of the character (this time played by Dina Waters) appears in the second episode of season 9 of Frasier, "Don Juan in Hell: Part 2," along with Neuwirth and Shelley Long reprising their roles of Lilith and Diane Chambers, respectively. In this episode, Rita Wilson also reprises her role as Frasier's mother, Hester, which she briefly debuted in the season 7 premiere, "Momma Mia;" in "Don Juan in Hell: Part 2," Diane also references the season 3 episode of Cheers, "Diane Meets Mom," in which Hester (then portrayed by Nancy Marchand) threatens Diane's life. Diane (again portrayed by Long) plays a central role in "The Show Where Diane Comes Back" (season 3, episode 14) and had a brief cameo in the season 2 episode "Adventures in Paradise: Part 2".
