Continuity mistake: When Bulldog wheels his things into the booth, there is nothing on top of the tape deck behind and to our left of Frasier's chair. As the shot changes and he says "you can vouch for that, Myrna", there is suddenly a blue cassette on top of the deck. The shot changes again and Roz puts her plate of cookies down on top of the tape deck - the cassette has disappeared.
Continuity mistake: When Roz begins her mock interview with Frasier, Niles is holding the microphone in her direction. After she says "from Bellingham", he moves it to the left for Frasier's answer. But the next shot shows that the mike is still pointed at Roz, and then we see Niles move it to the left again.
Continuity mistake: When Frasier and Roz are in his kitchen talking about audition tapes, sometimes he is holding a glass of sherry and sometimes he is not; it is not a case of him putting it down, as the scene goes to quickly for that. During the same scene, Roz's beer switches hands, and there was no time for that either.
Continuity mistake: At the end of the scene Niles opens the apartment door and waves his arm; the little white cloth is thrown and lands under him as he faints and hits the floor. Eddie heads for the couch and the shot shows the white cloth on the floor in the hall outside the apartment door. (00:11:20)
Continuity mistake: Niles is trying to convince Frasier to play squash - he has his hands on the back of Frasier's chair. Cassandra comes out of the kitchen and we see one of Niles' hands on Frasier's shoulder. In the next shot, both hands are back on the chair, even though there was no time for this to happen naturally. (00:02:35)
Continuity mistake: In the conference room, Frasier says, "I just said that," and the shot shows his arms resting on the table with his hands up, gesturing. The next shot, from the side, shows him leaning back in his chair with his arms right off the table. The shot then goes back to the original position. There was no time for him to move naturally.
Continuity mistake: While Ann is talking to Frasier near the door of his apartment, his coat is over the arm of the couch. After Frasier closes the door after Caroline's brief visit, the coat is over the back of the couch, even though no one went near it during that time.
Continuity mistake: Frasier and Martin are in the kitchen and Marty gets some chips out of the cupboard next to the fridge. As he leans down to pet Eddie we can see a bag of blue chips still in the cupboard - but when he straightens up to talk to Frasier, we see a red bag in the cupboard, not the blue one (the camera angle remains the same).
Continuity mistake: Niles is showing Marty how he can kick box and he accidentally kicks Daphne. The tray she is covering flies up in the air, and the snack food ends up on the footstool and the floor. There is also an empty basket in front of the footstool. Niles goes to the kitchen to get ice for her wrist; when he returns most of the snack food and the basket have disappeared.
Continuity mistake: Nanny G and Frasier are in the kitchen of his apartment and there is a tray with three empty wine glasses. Nanette takes one and pours herself some wine; a few seconds later Frasier grabs the tray and goes into the living room, but now he has four empty glasses on the tray when there should have only been two. At no time did he add glasses to the tray.
Plot hole: Niles phones Frasier to tell him Daphne is staying at his place because of the storm. Frasier's phone is in its usual place on the room divider/bookcase behind Marty's chair. After Frasier and Marty leave to rescue Daphne, Niles phones again and Eddie is standing up on a chair staring at the phone. Only problem is, the phone is over on Frasier's desk, where there normally is no phone. If he did have a phone there, it is only a few feet from the other one, which makes no sense.
