Revealing mistake: At Cafe Nervosa, after Niles has had a mini-breakdown, he has shed his clothes, boxers and all, all over the place and is supposedly naked in the corner with only a newspaper for privacy. When Frasier has him stand up to wrap aprons around him, one can see that David Hyde Pierce is actually wearing light-coloured briefs.

Visible crew/equipment: When Frasier is standing through his sunroof to speak with the drivers stuck behind him in the parking garage, one shot shows Frasier's body and much of the rear window which features a very clear reflection of the boom mic.
Frasier: And though washing one's hands twenty to thirty times a day would be considered obsessive/compulsive, please bear in mind that your husband is a coroner. Thank you for your call, Jeanine. Roz, whom do we have next?

Question: There's probably an obvious answer to this but is there any actual in-show significance to the 'Tossed Salads and Scrambled Eggs' song heard at the end of every episode? I ask mainly because I remembered there was one show in particular where Frasier unintentionally scars Lilith emotionally and pretty much cements the end of their relationship over a misunderstanding about scrambled eggs. Were there any similar conflicts over a tossed salad?
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.
