Continuity mistake: Martin opens the jewel case-like box twice in two different shots in the background. (00:09:55)
Continuity mistake: Niles has the "hot buns" pads under his right arm and his mittens in his right hand. The next shot shows he already has a mitten on his left hand even though there was not enough time for him to put it on. (00:10:25)
Continuity mistake: Right at the start, the tapes Roz is holding change hands at least twice. Although you can't often see both her hands, you sometimes see one and yet they still switch by the next shot.
Continuity mistake: When Niles brings out the "Hot-Buns," he hands it to Martin who instantly in the next shot, is pulling it out from under him when Daphne comes in. There really wasn't time for him to put it under himself first.
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!
