Jerry and Kramer in “Unfinished Business”

Jerry

I just think if you borrow my blender you should return it.

Kramer

Well what’s the difference -- Come on, we're like Cain and Able.

Jerry

Yeah, you know Cain slew Abel.

Kramer

No he didn’t. They were in business together… it was dry wall, or somethin’.

Jerry

Oh, no.

Kramer

All right then, what was it?

Jerry

Well I think Abel worked hard all summer harvesting his crops, while Cain just played in the field. Then when Winter came, Able had all the nuts; Cain had no nuts, so he killed him.

Kramer

The way I remember it, Cain, he was a successful doctor, but when he took this special formula, he became Mr. Abel.
