George Costanza...

Gary Fogel: I've been living a lie.
George Costanza: You've been living a lie? I've been living like twenty!

George Costanza: The sea was angry that day, my friends. Like an old man trying to send back soup in a deli.

Jerry: Why didn't you tell her your code?
George Costanza: I can't give away my code to her.
Jerry: George, you're gonna marry this woman... probably.
George Costanza: No way. The bank clearly says "Don't give away your code to anyone".
Jerry: So, you're taking relationship advice from "Chemical Bank" now?
George Costanza: Why does it always have to be "us"? Why can't there be a little "me"? Is that so selfish?
Jerry: Actually, that's the definition of selfish.

George: I happen to dress based on mood.
Jerry: But you essentially wear the same thing all the time.
George: Seemingly, but within that basic framework there are many subtle variations only discernible to an acute observer that reflect the many moods, the many shades, the many sides of George Costanza.
Jerry: And what mood is this?
George: This is morning mist.

E claro a melhor de sempre:

George Costanza: Hi, my name is George, I'm unemployed and I live with my parents.
