Continuity mistake: Frasier is sitting on the couch watching Wheel of Fortune and eating, with a plate on his stomach. As he talks to Niles he places the plate on the coffee table. Niles says "Are those profiteroles?" and Frasier gobbles them up. Then we see Frasier put the plate on the table again.
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.
Continuity mistake: After calling Martin the "Sultan of Brunei," Frasier grabs his wine glass with one hand on the top and walks out of the kitchen. In the next shot when he is coming out he is holding it by the neck and there was no time for him to change his grip.
Continuity mistake: Right at the start when Frasier is talking to Niles in the furniture shop, at one point he says "Don't you hear that," and holds his hand in a fist. The shot cuts instantly to Niles and you can see his hand is now about a foot higher and his palm is suddenly open.
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.
