Roz's Turn - S4-E17
Continuity mistake: When Roz and Frasier are in Bebe's office, and Frasier is exclaiming about her taking digitalis, the water glass in front of her is empty. The rest of the shots show it being about half full, even though she never refilled it, and there was no water source to be seen.

Continuity mistake: At the beginning of the show, when Niles and Frasier are in Cafe Nervosa, the man behind them has a paperback book which is open with all the pages fanned out, and then it is lying flat, then fanned out again, and so on.

Continuity mistake: Near the end of the show, Roz and Frasier are at the radio station, in his booth. There is a clipboard lying on the console to the left.

Continuity mistake: Frasier is recounting what happened in Cafe Nervosa and we see the flashback - he is explaining why Bulldog is not a hero. In the flashback, we see Bulldog grab hold of Roz and he throws his coffee supposedly towards the gunman. However, the shot shows the cup rolling back towards where Bulldog was standing. In the next shot, we see the coffee cup again, hurtling towards the gunman, and spilling coffee on him.
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.
Continuity mistake: When the KCAL team goes for their final weigh-in, Roz grabs some scissors and one of her co-workers cuts her hair - but he cuts it quite low towards the bottom of her ponytail - when she holds up the cut portion, she only has a few inches left to her ponytail.

Continuity mistake: Frasier is in the kitchen pouring mini chocolate chip cookies from a bag into a bowl while talking to Daphne. The motion of him pouring (and the sound) doesn't stop while he talks but when the shot changes the bag is on the counter next to him.
