Quotes

Mark: Derek and I always did have the same taste in women
Meredith: Excuse me?
Mark: You're Derek's lusty intern, right? I've heard about you all the way back in New York. You're famous.
Meredith: Well, I heard about you all the way here in Seattle, so I guess we have a lot in common.
Mark: We're the dirty mistresses.
Meredith: I suppose we are.
Mark: My 400 dollar an hour shrink says that it's because behind this rugged and confident exterior, I'm self destructive and self-loathing to an almost pathological degree.
Meredith: Hey, we do have a lot in common.
Mark: You know, it’s funny, Derek walks in on me naked with his wife, actually in the throes, and he just turns around and walks away. But he sees me so much as talking to you, and I'm on the ground bleeding. Interesting, don't you think?

Meredith: It's McSteamy. McSteamy! Yoo hoo!
Mark: McSteamy? That's what your calling me now?
Meredith: Yes, but I don't think you are supposed to know.
Mark: How's my favorite dirty mistress?
Meredith: Haven't you heard? Now I'm an adulterous whore!

Mark: She told you. I've known you my whole life, I grew up with you so I know what you're thinking. That there is a year of your life wasted. Trying to make it work with Addison and you could have been with Meredith. That you could be happy right now. That all this, everything. That you and Meredith could have had a real chance. Still, I thought you should know the truth. Thought I owed you that, as a friend.

Nancy: What are you doing here, Mark? Are you trying to torture him?
Mark: He's my family, Nancy. Plus I needed a change of pace. (Nancy gives him an unconvinced look) Plus I slept with my tennis partner's wife and he went out and bought a gun.

Meredith: Okay, before you start, there are rules to this friendship thing or whatever.
Mark: The Dirty Mistresses Club has rules? Gosh, I thought a bunch of dirty mistresses would be a little less uptight about these uh, rules.
Meredith: Number one, no flirting. Second, no talking about Derek and C, no giving me the face.
Mark: The face?
Meredith: The McSteamy face. Doesn't work on me. I'm immune.
Mark: You know, if I'd gone off to the woods, I would've invited you to keep me warm.
Meredith: Breaking rules 1, 2 and 3.

Mark: It's bring-a-hot-blonde-to-work day and no one told me?
Izzie: (feigns sneeze) Sexual harrassment.

Derek: It'd be nice if every love triangle could be fixed with a scalpel.
Mark: If they could, you would have stabbed me with a ten blade a long time ago.

Mark: What do you consider your weaknesses?
Addison: I don't have any. I'm that good. What are yours?
Mark: I'm an easy mark for evil redheads.
Addison: (laughs) Trust me, you have other weaknesses. Obviously, you are a manwhore.
Mark: Correction: I was a manwhore.

Derek: What did you do?
Mark: I spread the word you were lookin'.
Derek: You spread the word I was looking?
Mark: Lookin' ... it sounds much dirtier without the "g."
