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: 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.
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.
Answer: Nanny G (Nanette Guzman - played by Laurie Metcaf) has been a children's entertainer for twenty years, and tells Frasier, "Do you know what it's like to play the same character for 20 years?!" The joke is that Kelsey Grammer has been playing Frasier Crane since 1984, when the character first appeared on "Cheers", so Kelsey in real life has been doing just that!
