Frasier: Niles, get a hold of yourself! Stop it! Stop, stop. It's all right. You're no longer an awkward teenager, you're a renowned psychiatrist. Danny Kreizel may have won a battle or two back in junior high, but that's where he peaked. You won the war. You know the expression, "Living well is the best revenge"?
Niles: It's a wonderful expression. I just don't know how true it is. You don't see it turning up in a lot of opera plots. "Ludwig, maddened by the poisoning of his entire family, wreaks vengeance on Gunther in the third act by living well."
Frasier: All right, Niles.
Niles: "Whereupon Wotan, upon discovering his deception, wreaks vengeance on Gunther in the third act
again by living even better than the Duke."
Frasier: Oh, all right!
