Selling Out - S1-E9
Continuity mistake: Frasier meets Bebe for the first time in the hall at KACL. She has her business card in her hand for part of the scene but after Frasier tells her he has a son, the card disappears - with no time for Bebe to have put it back in her purse.

Selling Out - S1-E9
Continuity mistake: When Frasier and Niles are in the Cafe, Niles says something like "Why do you feel like that?" During this line Niles goes from putting sugar in his coffee to having the mug raised instantly.
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!
