Continuity mistake: Poppy is sitting in Frasier's chair in his booth and as she says "all these buttons, how do you do it?", she slaps her hand down on the console. As he begins to answer her, the hand is back in her lap.
Something Borrowed, Someone Blue (1) - S7-E23
Continuity mistake: When Frasier is in his apartment, trying to get Daphne away from Niles, the book and decorative pieces on his coffee table change position from shot to shot.
The Dog That Rocks the Cradle - S7-E5
Continuity mistake: Bulldog is near Frasier's apartment door with baby Alice and she is facing the door. When Roz walks towards them and asks, "Bulldog do you want a job?", Alice suddenly has her back to the door, with no time for the change.
Continuity mistake: Near the beginning of the show, Poppy meets Niles at Cafe Nervosa. She has a black purse which she places on the table in front of her. During the scene, the purse is sometimes on the table and sometimes isn't, even though Poppy never removes it.
Hot Pursuit - S7-E18
Continuity mistake: When Kenny comes to Roz's hotel room, Frasier answers the door and his pyjama collar is tucked in under his robe. A couple of shots later it is outside his robe, though he never touched it, and in later shots it is back neatly under his robe.
Continuity mistake: Frasier, Regan, Niles, and Poppy are at the ball - Frasier asks Regan to dance and she leaves her purse on the table, where we can see the strap hanging down over the edge. A couple of shots later, as they dance by, we can see the purse has changed position and the strap is lying on the table.
Something Borrowed, Someone Blue (2) - S7-E24
Other mistake: When Daphne comes to the Winnebago she doesn't close the door properly, you can see it opening slightly again. When she and Niles drive off, it's closed.
Three Faces of Frasier - S7-E21
Visible crew/equipment: Towards the end of the show, Marty and Frasier are sitting in the living room talking. Eddie is curled up right next to Frasier on the couch. There are a number of shots focused on Frasier and Eddie and on the bottom of the screen one can see something flick by a couple of times - and in one shot there is definitely a couple of inches of a grey metal pole of some sort, about the thickness of a broom handle.
Continuity mistake: When Marty is being interviewed at the Antiques Road Show, the expert's clipboard changes from being flat against his body to perpendicular to it - with no time for a natural shift in position.
Continuity mistake: During the opening credits, Roz is in Cafe Nervosa with a laptop. Next to it are 3 or 3 crumpled pieces of paper or Kleenex. A couple of shots later the pile shrinks to maybe one piece - without Roz or anyone else touching them.
Continuity mistake: Lilith takes on the job of pouring wine for Thanksgiving dinner - we see her pour 2 glasses but when the shot changes there are 3 full glasses of wine on the table even though there had been none before she started.
Other mistake: In the kitchen, when Niles burns his hand you can see him move his hand down to stop the frying pan from falling off the stove. He doesn't touch it again, but it looks like the instinctive actions of someone who knocked something over rather than part of the scene. He just slips out of character for a moment.
Hot Pursuit - S7-E18
Continuity mistake: When Frasier and Roz are in the hotel room talking, her champagne glass switches from her right hand to her left hand, from one shot to another, with no time to have happened naturally.
Dark Side of the Moon - S7-E22
Continuity mistake: Simon has shown up at Daphne's shower and is standing at the bar/table with Roz and Holly. There is a bottle of champagne on the table, next to an ice bucket - but when Daphne drags Simon away the shot shows that the bottle has mysteriously made its way into the ice bucket.
The Dog That Rocks the Cradle - S7-E5
Continuity mistake: Bulldog brings pizza to Frazier's apartment, and Niles pays him. As Bulldog says goodbye to Frasier, he puts the money in his pocket. When Roz comes out from the back bedroom and sees Bulldog, we see him put the money in his pocket again.
Hot Pursuit - S7-E18
Continuity mistake: When Roz is getting ready for the reception at the convention, her wrap is hung neatly over the back of the couch. After she answers the phone and passes it to Frasier, the wrap is suddenly opened up and draped much more messily over the couch. Her purse has also changed position on the coffee table.
Continuity mistake: Frasier is in the kitchen to get some herbal tea for Regan - the box is mauve - in the first shot it is laying on its side but after that it is standing upright, although Frasier didn't touch it during that time.
Something About Dr. Mary - S7-E16
Audio problem: After Mary says "Except I bet you didn't walk through a metal detector to get to class", Frasier in that shot does not move his mouth in line with the dialog that he speaks, but instead appears to be laughing. Additionally in the next shot, although his mouth now matches his dialog, he is half way out of his seat despite being sat in it in the previous shot. (00:02:15)
The Dog That Rocks the Cradle - S7-E5
Continuity mistake: During the opening credits Roz and Frasier are sitting on his couch working. Roz is telling him that she has a date the next day - he is holding a magazine. But as she says "a month", the shot goes back to Frasier and he's holding papers rather than the magazine.
Continuity mistake: When Frasier is offering to help Lorna carry her books, her purse switches from her right shoulder to her left arm and back to the right from shot to shot.
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.
