Continuity mistake: When Frasier and Roz are in the cafe talking about the See Bees, Roz says something like "Those shows are torture." When she does there are many different shots in a short space of time and if you're quick you can see the coffee mug suddenly jump into her hand without picking it up.
Character mistake: Frasier tells Niles that the article on him will be in the winter/spring issue of Seattle Broadcaster. The man who interviews him introduces himself as a journalist from the Seattle Times.
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.
