Dark Side of the Moon - S7-E22
Continuity mistake: Roz is at Daphne's shower, saying "God, he sounds just like a prince," in reference to Simon - in her left hand is a drink and her right hand is positioned down, as though it is in her pocket. In the next shot she is still holding her drink in her left hand, but is giving Daphne a drink with her right hand - it just appears out of nowhere.

Continuity mistake: While Frasier is talking to Daphne about wooing Holly, the wine bottle on the coffee table changes position more than once - from sitting on a book on the left of the tray to being on the bare table on the right and then back again to the left of the tray, but not on the book. Nobody touches it during this time.

Continuity mistake: When Roz comes over to meet Simon for their date, she is standing at the door talking and one strap from her shoulder bag is hanging down from the shoulder. The shot from behind her shows both straps are on her shoulder, and then the shot goes back to the front - it's down again. At no time did she adjust it.

Continuity mistake: When Daphne goes to Niles's place to see him, she sits down on the couch and slides her purse behind her. A couple of shots later Niles gets up and now we can see her purse on the couch to her left. At no time did she make any movements that could explain its change of position.
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.
