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: At the radio station, Roz waves her pencil at Frasier through the glass to wrap up his show; she has a KACL mug in her other hand. The next shot shows her actually leaning over to pick up the mug, without enough time for her to have put it down in the first place.

Continuity mistake: Marty and Niles are getting off the elevator and Marty transfers his mail into his left hand just as he goes to open the door to Frasier's apartment.

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.
