Space Quest - S1-E2
Audio problem: Just before Frasier opens the door to get his paper, he says "I'll get him for this and his little dog too". However, his mouth moves when he says "I'll get him for this and his...", but his mouth doesn't move when he says "...little dog too". (00:02:40)
Adventures in Paradise (2) - S2-E9
Audio problem: Madeline arrives at the apartment and says "Hello" to Marty, Niles and Daphne. However, her mouth is out of sync when she says it. (00:10:00)
Audio problem: Frasier is talking to Elliot on the phone and there is a shot of Roz. In the shot of Roz, Frasier says "You know, Elliot..." and his reflection is visible in the window. But his lips on the window reflection don't move until after he says "You know, Elliot..." (00:00:30)
Audio problem: Near the start of the show, Frasier is in the booth at KACL, and has told Roz off and is glaring at her through the glass. As the shot shows her face, however, we can see the reflection of Frasier in the glass - he is smiling and his lips are moving as though he is talking. However, there is no audio to match his speech.
A Word to the Wiseguy - S3-E15
Audio problem: Around the time when Niles is talking about "wealthy white women," there is a shot when his mouth is moving but there is no sound coming out. It then suddenly changes to a shot when you can hear what he is saying. (00:02:15)
Audio problem: As Frasier says, "Well, let's shoot it to the news," we can see his reflection in the booth, but his lips aren't moving as he speaks.
Audio problem: At the end of the show, Niles picks up the bottle of booze from his father's chairside table, and we hear a thud - as though he had put it down, rather than picked it up. The same sound is repeated a short time later, when he does put the bottle down.
Audio problem: As Frasier walks into Niles' kitchen, Daphne is on the phone, talking. We hear a hoarse sound, like Frasier's voice, saying "Daph" or "Dad" but it makes no sense as she is on the phone talking to someone, and he is heading for the fridge. When she hangs up, she and Frasier start talking about her employment situation.
Audio problem: Dr. Nora's mother is pounding on the glass of Frasier's booth. She then wags her finger at Nora but the sound of her pounding continues, even though she's no longer doing it.
Audio problem: When Frasier is in the hall explaining to Kenny and Gil why Poppy has her own show, we can see Poppy through the glass of the door. She is supposed to be doing her show, and we can hear the audio in the background. However, it is obvious that Poppy is not talking at all - she is sitting perfectly still with a very blank look on her face.
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 Bad Son - S8-E3
Audio problem: Frasier is standing in his living room talking to Niles. We hear a knocking or tapping. As Frasier is expecting his date, Miranda, this might make sense, but they do not seem to hear it and make no move towards the door. A short time later the doorbell rings and Frasier's date arrives.
Audio problem: In the opening credits Frasier is in Cafe Nervosa with Roz, who is trying to sell him gift wrap. He says, "I'm not crazy about Garfield," and then his lips keep moving even though there is no sound heard.
Legal Tender Love and Care - S8-E6
Audio problem: This does not sound like a case of Frasier stuttering but it sounds like two sets of the same line over top of each other. When Niles sees Donny come into the restaurant, Abby and Frasier just turn to look and Niles exclaims "I said, don't look." - and Frasier says "you - you did not - not". It's as though they forgot to edit out some sound from two different shots.
Audio problem: In the restaurant Frasier says "There's an ocean of fresh fish not 15 feet away," and you can even see the blue reflection of the water and it's movement as it laps against the shore. Why then, can't you hear waves crashing at all? This is especially strange as in every other scene in this restaurant you can year it, but not in this particular one.
Audio problem: When Frasier and Martin go to see the woman play the piano it's very badly dubbed. Quite often her hands are at totally the wrong end for the sound the instrument is producing.
Audio problem: Frasier is on the air and is talking to Roz who is in her booth. As he says "Meanwhile, this is Dr. Frasier Crane," we can see his reflection in the glass but his lips aren't moving, even though he is talking.
And Frasier Makes Three - S11-E20
Audio problem: There are two audio problems in this episode, both in the same scene. Frasier is in his apt. talking to Niles, Daphne, and Martin. After Marty says, "Wow, really?", we hear a couple of garbled words while Niles' lips move. Then as Frasier heads to the door, Daphne asks, "How'd he hurt himself anyway?" While she is saying this, we can hear a phone ringing faintly. It is not coming from on stage, no one moves to answer a phone, and it has no part of the plot.
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.
