Liar! Liar! - S4-E10
Continuity mistake: At the beginning of the show, the KCAL gang are in Frasier's apt. celebrating the SeaBee awards. Bulldog is gloating about his win. At one point he has his left hand out in front of him and up in the air - the next shot the same hand is behind his back.
Liar! Liar! - S4-E10
Continuity mistake: At the beginning of the show, we see Marty add some beer to his champagne glass until it's almost full - just then Bulldog grabs his SeaBee award from the coffee table and now Martin's glass is almost empty, even though he's had no chance to even take a drink.
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?!"
