Grey's Anatomy, Season 5

Denny:
Nice ring. Alex outdid himself.

Izzie:
We're gonna have beautiful kids, don't you think? Is four too many?

Denny:
Four is perfect.

Izzie:
Ideally it would be two boys, and two girls. One of which would definitely be a tom boy. And I was thinking I should have them pretty close together, though that might be stupid.

Denny:
Why wait?

Izzie:
Exactly. That way if I'm not able to practice medicine anymore...

Denny:
You won't want to.

Izzie:
You don't think?

Denny:
Do you?

Izzie:
I'm asking you. Why do you keep agreeing with everything I say?

Denny:
Because I am you. I'm your tumor. You're talking to yourself.

Izzie:
Right.

Denny:
At least until you have surgery. If you have surgery. Are you gonna have surgery?
