[after Patty breaks up with Jerry]
Jerry: [crying] What is this salty discharge?
Elaine Benes: Oh, my God. You're crying.
Jerry: This is horrible! I *care*!
George Costanza: You know, after all these years, I've always wanted to see the two of you get back together
Elaine Benes: Well that's because you're an idiot!
Lloyd Braun: You know, you should tell your dad that 'serenity now' thing doesn't work. It just bottles up the anger, and eventually, you blow.
George Costanza: What do you know? You were in the nut house.
Lloyd Braun: What do you think put me there?
Jerry: [Sarcastically] Kramer, I love you.
Cosmo Kramer: [Without missing a beat] I love you too, buddy!
Frank Costanza: SERENITY NOW! SERENITY NOW!
George Costanza: What is *that*?
Frank Costanza: Doctor gave me a relaxation cassette. When my blood pressure gets too high, the man on the tape tells me to say, 'SERENITY NOW!'
George Costanza: Are you supposed to *yell* it?
Frank Costanza: The man on the tape wasn't specific.
[Kramer has just taken his built-up anger out on the computers George intended to return]
George Costanza: Why couldn't you squeeze one of those stupid rubber balls to get your stress out? Whyyyyy did you have to destroy twenty-five computers?
Cosmo Kramer: [eating an orange] George, you listen to me. I owe you one.
