Private Practice, Season 2

Archer:
[to Addison] I like women. I like a lot of women. But I am not married to Naomi and she is not the mother of my children.

Addison:
Naomi sat by your side while you had surgery. She held your hand. You're upstairs sticking your tongue down her throat, seeing her every day, letting her believe that you two have something together.

Archer:
Well, I thought I was dying.

Addison:
You are... you are asking me to lie for you. You are making me feel dirty, and cheap, and I'm ten years old again. Telling Mother that I went out for ice cream with Daddy, when really I'm sitting in his office while he's screwing his secretary down the hall.
