George O'Malley: You know what you need?

Meredith Grey: No. It's sick and twisted. We said last time was the last time. You've been doing it without me?

George O'Malley: Nancy Reagan lied. You can't just say no. Come on.

Meredith Grey: Do you know what would happen if anyone knew?

George O'Malley: I'm doing it. You can come with me, or you can stay here and be miserable.

(In next scene George and Meredith are looking at the newborn babies and George is babbling at them...)

Meredith Grey: You are such a woman.
