Continuity mistake: Frasier comes home to find his sherry decanter empty and opens a bottle of wine, which he leaves on the kitchen counter. Niles arrives, wants sherry, and Frasier tells him there is none, saying, "I've opened some wine, help yourself." Niles grabsthe open bottle from the bar area, even though no one had put the bottle back - it should have still been on the kitchen counter.
Continuity mistake: Frasier and Martin are in the kitchen and Marty gets some chips out of the cupboard next to the fridge. As he leans down to pet Eddie we can see a bag of blue chips still in the cupboard - but when he straightens up to talk to Frasier, we see a red bag in the cupboard, not the blue one (the camera angle remains the same).
Continuity mistake: Frasier and Niles are in the kitchen at the cabin. Niles picks up his mug to take a sip, but in the next shot his mug is still on the table.
Continuity mistake: When Frasier and Marty are talking about going to Ronee's cabin, Ronee is sitting on the right side of the couch with nothing behind her. In the next shot, she gets up and we can see a light brown overcoat. This coat disappears again in the next shot, as Frasier answers the door and Niles comes in, carrying the very same overcoat which he places on the right side of the couch, where Ronee had been sitting.
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!
