No kidding? Outstanding! How're you gonna do it?

I don't know. Just decided.

Mark:
Shepherd's proposing.

Owen:
Congratulations, that's a big step.

Derek:
Thank you very much. [to Mark] You just gonna tell everybody now?

Mark:
You need advice. Hunt, you ever proposed before?

Owen:
Uh sorry I'm... not the guy to ask. When are you gonna do it?

[Meredith approaches]

Derek:
Well more importantly how am I gonna do it?

Mark:
