Other mistake: Frasier seems jealous in this episode that Dr Webber went to Oxford, he even says, "Oh well, even better," in comparison to his own Harvard. However, in several other episodes we are told that Frasier got degrees from both Harvard and Oxford so why the jealously? Similarly in other episodes, he never mentions Oxford, only Harvard as where he went to University.

Frasier: Roger, at Cornell University they have an incredible piece of scientific equipment known as the Tunneling Electron Microscope. Now, this microscope is so powerful that by firing electrons you can actually see images of the atom, the infinitesimally minute building blocks of our universe. Roger, if I were using that microscope right now, I still wouldn't be able to locate my interest in your problem.

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.
