Cristina: What the hell is this?
Burke: It's a key.
Burke: Why is it a key? Are we feeling existential this morning?
Cristina: Well, if the key turns in a lock, and no one asked for the key or even wanted the key, does it make a sound?

Izzie: I shall name him...running guy.
Derek: So, when did you last ejaculate?
Patient: I'm not sure. Meredith?
Bailey: Well we've tried everything, it must be neural.
Cristina: She already called for a consult.
Derek: Hello everybody, what's up?
Meredith: Burke keyed you?
Cristina: I got freaking keyed before coffee.
Cristina: Congratulations, you're flaccid.
Patient: Never thought I'd be glad to hear that.
