Continuity mistake: Near the beginning of the show, Frasier brings Roz a muffin in a bag which she places to the left of her phone (her left). During the scene, the bag shifts from being near the console to being back to left of the phone. At one point Frasier and Roz leave the booth, then come back in, and it has moved in the meantime.
Continuity mistake: Near the start of the show Marty brings two green mugs over to Daphne at Cafe Nervosa, gives her one and keeps one for himself. We see his hand on the mug but in the next shot the same hand is on his knee.
Continuity mistake: At the start, when they are discussing the show you can see that Martin is holding his coffee mug, but when it cuts and he says "It's your 1000th show," his hand is suddenly near his lap.
Continuity mistake: Near the start of the show, Roz is reading the note Bulldog has left with the teddy bear. She is holding the note in both hands with the bear between her arm and chest. As she says "love, Bulldog", the shot shows one hand hugging the bear against her, with no time for this to have happened naturally.
Continuity mistake: When Frasier is reading from the psychiatric journal that contains Niles' letter, at one point he is holding it in both hands by the front cover - the shot changes and he has one hand on the front cover and one hand on the back cover, without time to switch naturally.
Continuity mistake: Early in the show, when Frasier comes into the booth and gives Roz a muffin, the note from Bulldog has changed position on her clipboard even though no one goes near it.
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!
