Continuity mistake: Niles is filming is father in his recliner, trying to record his life story for posterity. Marty fakes a heart attack or death - and lies back in his chair with his left arm by his side. In the next shot his arm is crooked up around his head, but with no time for him to have moved it.
Continuity mistake: After calling Martin the "Sultan of Brunei," Frasier grabs his wine glass with one hand on the top and walks out of the kitchen. In the next shot when he is coming out he is holding it by the neck and there was no time for him to change his grip.

Continuity mistake: Martin and Daphne are laughing at Eddie who has taken a pill to calm him down - in one shot he has a paw up in the air, but in the next shot both paws are pointing sideways. The shot changes again, and Eddie is back in the first position. He had to time to change naturally.
Continuity mistake: When Marty comes into the living room, he puts the container of jerky down on top of the book on the right side of the coffee table. A few minutes later, when Donny takes a piece, the container is on top of the book on the left side of the table. No one went near it in the meantime.
