Kramer

Hey everybody. (to Jerry) Listen, uh, do me a favour, will you? I got a hot date tonight with Connie. Knock on my door, wake me up in twenty minutes, alright?

Jerry

Catnap?

Kramer

No, no, no, no. (comes in) This is evolutionary. I been reading this book, on Leonardo de Vinci. See, that means 'from Vinci', d'you know that?

Jerry

(deadpan) That must be some book.

Kramer

Yeah, well, turns out that the master slept only twenty minutes every three hours. Now, that works out to two and a half extra days, that I'm awake per week, every week. Which means, if I live to be eighty, I will have lived the equivalent of a hundred and five years.
