Continuity mistake: At the very start of the show, Frasier is pretending to conduct an orchestra with a wooden spoon. Marty says "Boo," and we see the spoon in his right hand. Then Ronee says, "He does scream like a woman," and suddenly the spoon changes to his left hand and is turned the other way. Frasier had no time to change it.
Continuity mistake: At the hospital the nurse comes over to talk to Frasier about his father - her paper on her clipboard is flipped over the back of it and her hand is holding the side of it. A couple of shots later, with no opportunity to change positions, the paper is no longer flipped over and her hand is lying on top of the clipboard.
Boo! (a.k.a. I'm With Her) - S11-E16
Continuity mistake: Marty is home from the hospital and there is a basket of flowers on the coffee table. The basket moves several inches to the left while Niles goes to the door to let Ronee in.
Boo! (a.k.a. I'm With Her) - S11-E16
Continuity mistake: In the first scene after Niles walks in and takes his coat off. The left-hand side of his shirt collar alternates between tucked underneath his jacket and sitting outside 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!
