The Letter

And the lady went, 'Really?' I mean, even the Ginsu people have given up.

Perhaps you're not buying the highest grade of meat available.

Maybe you ought to think about not getting the 'hoof cut' once in a while.

What is it about sleep that makes you so thirsty? Do dreams require liquid?

Jerry waking up to find Kramer in his apartment

I was watching Thirty Seconds Over Tokyo... and I wanted to get some popcorn... so I used the spare keys

Is that my towel? - Yes.

You ever pretend there's murderers chasing you and see how fast you can get into your apartment?

The entire key exchange argument and physical struggle

I broke the covenant of the keys.

I was clinging to those keys, man... like a branch on the banks of a raging river... and now I have let go. And I'm free to go with the current... to float.

Having the keys to Jerry's apartment... that kept me in a fantasy world... Better food, better view, better TV. Cleaner. Oh, much cleaner.

I was living in twilight, George. Living in the shadows, living in the darkness... like you.

Do you ever yearn? - Yearn? Do I yearn? - I yearn. - You yearn? Oh, yes. Yes, I yearn. Often I sit and yearn.

I crave all the time. Constant craving. But I haven't yearned.

The entire interrogation sequence where Kramer systematically destroys George's life

Do you have any conceivable reason for even getting up in the morning? - I like to get the Daily News.

'These pretzels are making me thirsty'? That was one line. You got fired.

Up here, I'm already gone.

I gotta get some new friends.

Newman's entire scene as Kramer's apartment occupier

Yeah, yeah, I saw it. I mean, it was complete bull... But I saw.

Ask her about Kramer. - She's drunk out of her mind.

The entire motorcycle ride with the psychotic driver

Lean! Lean!

The entire key logic argument between Jerry and George

Wanna fight? - I'll fight you! - Let's go. - Nothing in the face! - Okay.

If that ogre dude pulled that crap on me... I'd stab him! I'd cut him in half! I'd gut him like a fish, man!

You think these hands have been soaking in Ivory Liquid, huh?

Maybe because it's a crock of sh... - What's that? - Nothing.

Well, nothing's sexier than a woman behind the wheel of a semi. - Nothing? - Well...

Unless I pull down on this statuette and a hidden wall opens up... we have checked every square inch of this apartment.
