Frasier: Lilian, the next time your perfectionist tendencies drive you to distraction, just remember this quotation from Henry James: "Excellence does not require perfection."
Lillian: "That's very helpful. Thank you."
Frasier: Or is it "demand"? Hmm. "Require"? "Demand"? "Excellence does not require perfection." "Excellence does not demand perfection."
Roz: Aren't they the same thing?
Frasier: Of course not, Roz. Shush! "Excellence", "demand", "require", "demand", "require"- Oh! Or is it "mandate"?
Lillian: "I really have to go now." [call disconnects]
Frasier: Oh, well, it doesn't really matter, anyway, does it? Meantime, Seattle, this is Doctor Frasier Crane, wishing you good day- Oh! It's "require". It is "require"! And good mental health.

Frasier: Listen, I'm afraid I've got some bad news. I could only get two tickets for the spelling bee competition tomorrow.
Daphne: Oh, that's a shame. But we'll be there in spirit. It's probably just as well considering how emotional I get watching children compete. I keep thinking how much it means to them. Like the little girl who studies over candle light while her father's down at the local pub, drinking away the money for the light bill. Or the little girl on the school bus who pretends not to see her father waving at her from the pub. Then there's the little girl who thinks that by doing well she can grow up, purchase the local pub, and turn it into a circus so her father can keep his promise. [sobbing, exits]
Niles: We had a little wine at lunch.

Frasier: Frederick Crane, from Massachusetts, your word is "onomatopoeia"
[Freddie stands up and takes a breath.]
Frasier: Wrong. Where are your knees? I want to see spelling knees.
Frederick: Oh, yeah, right.
Frasier: The last thing I want is you passing out on stage because of locked knees.
Frederick: I know. Allison Sharpe, the "'Frisco Fainter".
Frasier: She went down like a sack of hammers.
