I have plenty, but these 2 pop to mind.
Newman: What are you proposing?
Jerry: Whatever it takes, for as long as it takes me, where ever it takes me as long as it takes you away from me!
Newman: An alliance?
Jerry: An Alliance.
(Both laugh evily while shaking)
Jerry: Now get the hell outa here!
Kramer: Newman called me last night again at 3 oclock in the morning threatening to jump off the building
Jerry: What did you say?
Kramer: I said 'Jump.'! Well, he’s been threatening to do this for years.. I said 'Look, if you’re gonna kill yourself do it already and stop bothering me.'.. At least I’d respect the guy for accomplishing something.
Those 2 get me all the time!
