Grey's Anatomy Season 6 Episode 7 Quotes

Now you completely lost your mind. You're drawing on the wall!

Meredith

I wore a diaper yesterday, yes - and I will wear one today. If it helps Dr. Shepherd get through the surgery, I will wear a diaper. My diaper is awesome. My diaper is hard-core. You wish you had the balls to wear my diaper. I'm gonna wear it, and I'm gonna wear it with pride. And if I have to pee in it? Oh, I'll pee. Because I am a surgeon. This is America. And I will do what needs to be done. So you can kiss my hard-core, diaper wearing ass.
