Grey's Anatomy, Season 1

Derek:
Miranda.

Bailey:
Excuse me?

Derek:
Well, that's your name right? It's on your jacket. Fine, I'll just call you Bailey then.

Bailey:
You know, you think you're charming, in that talented, neurotic, overly moussed hair sort of way. Good for you. But if you think I'm gonna stand back and watch while you favor her...

Derek:
I don't favor her. She's good.

Bailey:
I'm sure she is.

Derek:
You know, can I point out, that technically, I'm your boss.

Bailey:
You don't scare me. Look, I'm not gonna advertise your extracurricular activities with my intern. However the next time I see you favoring Meredith Grey in any way, I'll make sure she doesn't see the inside of an OR for a month. Just for the sake of balance.
