Fool Me Once, Shame on You, Fool Me Twice... - S2-E14
Continuity mistake: Daphne visits the radio station where Frasier works about halfway through the episode. She holds the earphone piece up to her right ear, then it cuts to a different camera angle and the headphones are lying on the desk with no time between shots. It's actually quite glaring.
You Scratch My Book... - S2-E15
Continuity mistake: Niles is holding his raffle ticket booklet over its envelope as he picks up Honey Snow's tape. As he says "insightful, isn't she?" the raffle booklet is suddenly under the envelope. (00:01:10)
You Scratch My Book... - S2-E15
Continuity mistake: Niles is looking through Honey's book and closes it with his finger holding his place as Frasier says "I skirt the issue". The next shot shows Niles with the book open at a different page, with no time for the change. (00:08:05)
You Scratch My Book... - S2-E15
Continuity mistake: Honey puts both hands on Frasier's shoulders, but the next shot shows one around his shoulder and one around his back, with no time shift positions naturally. (00:18:55)
You Scratch My Book... - S2-E15
Continuity mistake: While Niles is filling out raffle tickets on the coffee table, sometimes the envelope is on his left and sometimes almost completely out of sight on his right, although he never moves it around.
You Scratch My Book... - S2-E15
Continuity mistake: Honey walks over to Frasier, a glass of wine in one hand. Then suddenly she uses both hands to rub his shoulders. Supposedly she gave him the glass because it is all of a sudden in his hand now, but we never see him take it from her.
The Show Where Sam Shows Up - S2-E16
Continuity mistake: At the end of the episode after Sam mentions stewardesses he claps his hands, and his seat belt (which was caught on something) moves across his chest to the regular position. Cut to a wide shot of the car and Sam's seat belt is back to the position it was in before. (00:21:05)
The Show Where Sam Shows Up - S2-E16
Continuity mistake: Near the end of the show, at the end of the scene in Sam's hotel room, Frasier sits down on the couch; his raincoat is over his hands and wrists. The next shot shows his left hand and arm lying on top of his coat.
Continuity mistake: Frasier gets caught in Daphne's Room for the second time and crouches down beside her bed with the quilt over his head. He then sneaks into the bathroom - the quilt is left hanging over the edge of the bed. Shortly afterwards he runs out of the bathroom and the quilt is now folded over, completely on top of the bed, even though no one went near it. (00:13:30)
Continuity mistake: Niles runs to Daphne's Room with a full glass of sherry. He jumps into and out of the room and suddenly the glass is empty, even though he never drank from it, and it wasn't spilled. (00:20:40)
Continuity mistake: Roz, Niles and Frazier are in Cafe Nervosa having coffee. Niles has his hand open against his cup while Roz is making a suggestive remark but in the next shot his hands are laced together on the table.
Visible crew/equipment: During the closing credits, Frasier is sitting on his couch with a platter of meat beside him. Eddie is sitting up and begging for it and while he is doing this we can see the distinct shadow of his trainer's hand and arm against the couch. The hand goes higher and Eddie waves his paws higher and as the hand goes down, Eddie lowers his paws. Eddie keeps his eye on the trainer during this whole sequence. Once Frasier gives Eddie the platter of meat, the shadow disappears.
Continuity mistake: When Frasier's date calls and cancels, we can see his overcoat covering the back of the couch, but in the next shot, as he says "fat chance", the coat has changed position and we can see several inches of the top of the couch.
Someone to Watch Over Me - S2-E19
Continuity mistake: Frasier and Roz are in his booth and Roz puts her chocolate bar on the counter. While Frasier is on the radio, we sometimes see it at his left elbow and sometimes it is not, even though the angle doesn't change. (00:02:20)
Continuity mistake: Martin opens the jewel case-like box twice in two different shots in the background. (00:09:55)
Continuity mistake: Niles has the "hot buns" pads under his right arm and his mittens in his right hand. The next shot shows he already has a mitten on his left hand even though there was not enough time for him to put it on. (00:10:25)
Continuity mistake: Right at the start, the tapes Roz is holding change hands at least twice. Although you can't often see both her hands, you sometimes see one and yet they still switch by the next shot.
Continuity mistake: When Niles brings out the "Hot-Buns," he hands it to Martin who instantly in the next shot, is pulling it out from under him when Daphne comes in. There really wasn't time for him to put it under himself first.
Answer: In the last episode, they explained that Tossed Salad and Scrambled Eggs is a metaphor for the mixed-up people to whom Frasier dispenses his radio psychiatric advice.
