Grey's Anatomy Season 3 Episode 6

Derek: That was mean.
Nancy: Kathleen and told me to find out why the slutty intern's panties were hanging on the hospital bulletin board.
Derek: Four sisters. Four sisters, not one brother. And you wonder why I don't call more.
Nancy: Feel free to explain about the panties at any time.
Derek: Nance, you know what, it's great to see 'ya. It's really great to have you here. But I have a job, and patients.
Nancy: I have a patient at 35 weeks with twins. Where is her OB?
Derek: Well, her OB should be on a plane back to Connecticut where she belongs.
Nancy: Okay, so we've covered the trailer. We still need to cover the slutty intern, and the divorce.
Derek: You know, you're starting to sound more and more like mom everyday.
Nancy: Take it back.
