Our Parents, Ourselves - S6-E12
Continuity mistake: At the end of the restaurant scene, where Frasier, Roz, Martin and Roz's mother are eating, Frasier puts his crumpled-up napkin on one side of his plate, but at the end of the scene it has mysteriously switched to the other side without being moved by anyone.
Our Parents, Ourselves - S6-E12
Continuity mistake: Early on in the show, Roz and Frasier are talking in her booth at KCAL. At one point she picks up a pencil and holds it for a couple of shots, but soon it has disappeared with no movement to put it down.
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!
