The Life of the Party - S5-E22
Continuity mistake: At the singles party Frasier throws, Roz tells him she's in labour. She is not holding anything, but soon a small purse appears in her right hand, out of nowhere. When Vicky says "good luck" to her, the purse is nowhere to be seen.
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!
