Continuity mistake: At Frasier's apartment, Emily asks him if Marty is dating anyone. During the conversation Frasier's hands are in his pockets, and then in front of him, and then back in his pockets, from shot to shot.
Continuity mistake: Marty is on the couch talking to Edward about how he came out, and in several shots his hands are laced together on his stomach. In the succeeding shots, with no time to change, his arms are folded up on his chest.
Continuity mistake: In the beginning scene, Niles and Frasier are arguing by the door. Right after Niles leaves and Frasier yells "Get out! ", the camera pans out and you can see the entire room, at which point Roz is holding her wine glass in her right hand. Immediately after, the camera cuts to Roz who says, "yeah, some nerve..., " and the glass is now on the table in front of her left hand. There wasn't time for her to set it down (especially across her body), and the camera stays focused on her continuously through both shots.
Continuity mistake: In the opera, when Marty waves at the ladies, Fraiser tries to pull his hand down. He looks over at the ladies as he does this, but in the next shot he is turned towards Marty.
Answer: Nanny G (Nanette Guzman - played by Laurie Metcaf) has been a children's entertainer for twenty years, and tells Frasier, "Do you know what it's like to play the same character for 20 years?!" The joke is that Kelsey Grammer has been playing Frasier Crane since 1984, when the character first appeared on "Cheers", so Kelsey in real life has been doing just that!
