The Library Season 3, Episode 5

Jerry

What is your problem?

Bookman

What's my problem? Punks like you, that's my problem. And you better not screw up again Seinfeld, because if you do, I'll be all over you like a pitbull on a poodle.

Jerry

(after Bookman exits): That is one tough monkey! (turns to Elaine) So you were saying?

Elaine

Oh? So, I took your suggestion and I gave my boss Marion's poems. The ones that affected Kramer so much.

Jerry

Oh, beautiful did he like them?
