Continuity mistake: Marie and Frasier are sitting on the couch when Marty comes home, and her arms noticeably change position as the shot changes.

Continuity mistake: In the opening scene, Roz and Frasier are in Cafe Nervosa, and she is snoozing, while a half-eaten muffin sits in front her.

A shot then shows the muffin as half-eaten again, even though no one has touched it.

Continuity mistake: In the opening scene, Frasier is having coffee with Nancy and Roz comes in - she sits down and goes to put her purse on the floor. In the next shot her arms are suddenly up on her table and her hands near her face - without enough time for this to have happened in real time.
