Seinfeld, Season 9

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.
