Jerry: "Quone"? No, I'm afraid that I'm going to have to challenge that.
(Jerry picks up the dictionary.)
Kramer: No, you don't have to challenge that. That's a word. That's a definite word.
Jerry: I am challenging.
Kramer: Quone. To quone something.
(Jerry looks up the word.)
Helen: I'm not playing with you anymore.
Morty: Quone's not a word.
Jerry: No good. Sorry. There it is. Get it off.
Helen: (to Kramer) Why did you make me put that down?
Kramer: Nah, we need a medical dictionary! If a patient gets difficult, you quone him.
