Corrected entry: In a previous episode when Frasier confronts Charlotte over his bad dates they have a long discussion about how she has moved back to Seattle because of a divorce and is living with her "crazy assed mother", yet in this episode we see Charlotte's apartment where there is no sign of her mother and only one bed.
Corrected entry: The younger girl that Frasier goes on a date with has to be 20 years old or younger, since she mentions that cops took a fake ID from her (she wouldn't need a fake one if she were 21). Isn't it unlikely that someone that age would have been able to pay the $10,000 fee for Charlotte's dating service?
Corrected entry: Frasier is with Niles at Cafe Nervosa, and he is telling him that he overheard Ronee make a date with Richard. Niles then argues that he wants no part of this issue and Frasier says, "You can't outscramble an egg" - when he should have say "unscramble". He was referring to Niles going back and undoing something already done. One could argue that we misspeak in real life, but this is a performance, not real life and it is a mistake of the performer (or the writers).
