Continuity mistake: Early in the show, Niles has his hand up on his tote bag talking about the mosquitoes at the cabin, but the last shot shows him with his arms down by his sides, with no time for the change.
Continuity mistake: Marty brings a six-pack of beer to the cabin, and puts it down on the table where it stays for the scene - but during the scene one of the cans is sticking out for a few shots, then returns to normal later. No one went near the beer during that time.
Visible crew/equipment: As Frasier walks into the kitchen near the start you can see a crew member with arms folded at the side of the table on the other side of the lamp. (00:03:55)
Continuity mistake: Frasier is opening a bottle in the kitchen while talking to his father. He takes the cap off the same blue bottle twice. (00:05:07)
Continuity mistake: When Frasier and Martin are in the kitchen talking about Daphne's wedding gift, Marty is holding an open jar of beef jerky. In the middle of the scene, the lid is suddenly back on it, even though neither of them had time to do it.
Continuity mistake: Frazier and Marty go into the kitchen. Frazier gets out a blue bottle of water, uncaps it, puts the cap on the counter - and in the next shot we see him do the same thing again. He then goes into the living room and mistakenly tells Daphne he is going to pay for her wedding. She hugs him, and he is still holding the bottle of water. The next shot of her hugging him shows nothing in his hands, and when she lets him go, he whirls around and grabs his bottle of water off the bookcase.
Continuity mistake: Roz and Daphne are standing in front of the elevator talking about the wedding. Daphne is holding Frasier's choice of a bridesmaid's dress. In one shot, Daphne is holding it over her arm, but when she turns toward the door, with no time to change position naturally, she is holding the dress by the hanger.
Continuity mistake: While Frasier and Martin are in the living room talking about Frasier's offer to pay for the wedding, his blue bottle of water moves from one end of Marty's little table to the other.
Continuity mistake: When Marty comes into the living room, he puts the container of jerky down on top of the book on the right side of the coffee table. A few minutes later, when Donny takes a piece, the container is on top of the book on the left side of the table. No one went near it in the meantime.
Continuity mistake: Near the beginning , Daphne is talking to Frasier about her mother. As she says "she did bite through a kitchen spoon", her hand is up on her stomach, but in the next shot it's on her hip, with no time for a shift in position.

Continuity mistake: When Marty comes into the living room and says, "Man, they got you good", Frasier has his cup and saucer in his hand. When the shot changes, though, the cup and saucer are sitting on the table, a few inches away from his hand.

Continuity mistake: Frasier is sitting at his table composing a letter to Carlos and the Chicken, while talking to Niles about it. The two large reference books on the table in front of them change positions during the scene, without them touching the books.

Continuity mistake: Similar errors occur in two different scenes: in the first breakfast scene, the coffee pot is sitting on the table but in the next shot Daphne is pouring herself a cup, with no time for her to have naturally picked it up. Later in another scene, Niles is there for breakfast, picks up the pot, and pours himself some coffee. In the next shot, the pot is on the table, again without enough time for him to have put it back.
Continuity mistake: When Frasier and Poppy are sitting on his couch having a drink, the level in the wine bottle goes down and up and down throughout the scene, with no logical reason.
Continuity mistake: When Frasier first meets Poppy, she says something like "but not in the brewery thank you very much." When she does this you can see she's holding her hand out in front, in the next shot it's by her side instantly.
Continuity mistake: When Poppy is just about to start her show and is being emotional with everyone, Roz is standing at the door with a corded phone to her ear throughout the scene. She yells "Ten seconds." and the shot shows the phone, cord and all, has completely disappeared.
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.
Continuity mistake: Frasier is sitting on his couch with Poppy, dropping hints about having an arts show on KACL - she has her hands folded on her knee. As Daphne says "he means your mother", the shot changes, and Poppy is suddenly holding a glass of wine, with no time for this to have happened.
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.
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.
