Visible crew/equipment: Towards the end of the show, Marty and Frasier are sitting in the living room talking. Eddie is curled up right next to Frasier on the couch.

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.
