Continuity mistake: At the very start of the show, Frasier is pretending to conduct an orchestra with a wooden spoon. Marty says "Boo," and we see the spoon in his right hand. Then Ronee says, "He does scream like a woman," and suddenly the spoon changes to his left hand and is turned the other way. Frasier had no time to change it.
Continuity mistake: At the hospital the nurse comes over to talk to Frasier about his father - her paper on her clipboard is flipped over the back of it and her hand is holding the side of it. A couple of shots later, with no opportunity to change positions, the paper is no longer flipped over and her hand is lying on top of the clipboard.
Boo! (a.k.a. I'm With Her) - S11-E16

Boo! (a.k.a. I'm With Her) - S11-E16

Continuity mistake: While Niles, Daphne and Marty are watching the video of Cindy's labour, the bag of Marty's cookies change position a few times - from being in his chair to being on his little table, and back again.
Match Game - S11-E18

Match Game - S11-E18
Continuity mistake: The scene where Charlotte comes to Frasier in the restaurant to tell Frasier his date has cancelled is poorly edited between shots. Watch the folder once she has pulled it out: in almost every shot, the side facing the camera changes, and when Charlotte gets up, it disappears completely.
Continuity mistake: In the opening scene, Ronee and Frasier are talking at his table about her mother. Frasier asks, "She doesn't approve of premarital sex?" and his arm is folded in front of him. In the next shot, his elbow is on the table and his hand up in the air. Later on in the scene, Ronee's mother shows up at the door and we see Marty lunge to the right to grab his cane. A couple of seconds later the shot goes back to him and we see him lunge to the right for his cane again.
Continuity mistake: Frasier and Marty are sitting in their living room talking about Frasier's problems with women. Marty has his fork poised above a plate with a slice of cake on it. The next shot shows the fork on the plate, next to the cake. Marty would not have had time to put the fork down in the split-second in between.
Continuity mistake: When Niles and Frasier are in the cafe discussing how many patients have fallen in love with them, Frasier claims 13. But in the episode "The Maris Counsellor," he states no patient has ever fallen in love with him. OK, time has passed, but he's done hardly any private practice since then, and any he did do was shown anyway.
And Frasier Makes Three - S11-E20
Continuity mistake: Frasier picks up a couple of paper bags full of stuff for a picnic he is going on with Charlotte and her boyfriend - there is a fabric string/tie hanging out of one of the bags as he heads for the door but when he gets there, it has disappeared.
Continuity mistake: For "Crock Tales" (11x22). In the 2002 flashback Niles and Daphne have just slept together. Actually they first had sex in 2001.
Goodnight, Seattle: Part 1 - S11-E23
Continuity mistake: (This is for "Goodnight Seattle.") When Eddie is eating the pate with the ring in it, in the wide shot we see that he's finished all the food and is licking the plate clean. It then cuts to a closeup, and the plate is suddenly full of food. Back to the wide shot, and he's licking a clean plate again.
Goodnight, Seattle (1) - S11-E23
Continuity mistake: When Daphne, Niles, and the vet are in the examining room the items on the table in the foreground change positions in different shots.
Goodnight, Seattle (2) - S11-E24
Continuity mistake: When Eddie eats the wedding ring at Martin's wedding, there's no food on his plate, next shot there is.
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.
