Visible crew/equipment: When Frasier and Daphne are sitting talking in the sitting room, Frasier stands and the camera angle shows the fake wall above the fireplace - you can see the flue and that the wall stops just over where the shot normally finishes. There is visibly no proper wall behind the fireplace, you can see clear through to the construction behind.
Frasier Gotta Have It - S5-E19
Continuity mistake: Toward the end of the episode, Frasier and Caitlin are talking at her apartment about their status and she is sitting on the side of his chair. He has his right hand between her knees and left fingers tapping on her left thigh when he says, "well, I have been terribly worried about this global warming situation." Immediately in the next shot when she responds to him, she is holding his left hand with hers, and his right hand is down on the chair.
Continuity mistake: In the scene where Daphne is admiring her faux sapphire earrings, she says that it is the 5-year anniversary of her starting her work at Frasier's apartment. She actually started working in the 1st episode - which was in the fall. This episode takes place in the spring.
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!
