Seinfeld, Season 1

Elaine:
What evidence is there that cats are so smart, anyway? Huh? What do they do? Because they're clean? I am sorry. My Uncle Pete showers four times a day and he can't count to ten. So don't give me hygiene.

Jerry:
So what are you gonna do?

Elaine:
I don't know. I can't think of any solution, unless of course they should meet with some unfortunate accident. What do you think a hit man would charge to rub out a couple of cats?

Jerry:
Well, it couldn't be too expensive. Thirteen, fourteen bucks a cat?

Elaine:
What do you think, Jerry? You wanna make twenty-eight bucks?

Jerry:
I'm no cat killer.
