You should wear your hair up more. Shows off the back of your neck. I like the back of your neck.

Owen (to Cristina)

Callie: You're an idiot. What is your problem?
Mark: He is proposing to her. That makes Little Her, his little sister. And I can't sleep with any more sisters. And she's young. And I'm her boss.
Callie: And I'm celibate.

Lexie: You're the only one who knows about us and I'm terrible at keeping secrets. Keeping secrets makes me sick.
Callie: Look. Alone people don't like to hear about the together people. Okay. Even if the alone people are alone by choice. It's just sort of mean. It's sort of like bringing a 6-pack to an AA meeting.

Lexie (talking about Mark): He's fun and he's funny. Even with no sex we just laugh and we talk.
Callie: Yeah. I don't want to hear this.

Callie (to Owen): Can you do it?
Mark: Him? No. He's a meatballer.
Callie: He is meticulous and he will keep his mouth shut.
Owen: I've done operations like this before. It's not that complicated.
Mark: Guys run into this problem on the battlefield, do they?
Owen: I don't think you and I should talk about how guys run into this.

Mark: Pain and agony for a little bit of pleasure? I get it.
Callie: If it's that bad, why don't you stop sl- ... doing what you're doing.
Mark: Because it doesn't feel bad when I'm ... doing it. It's good. It's great. And maybe if you weren't so scared of getting burned, you'd feel the same.

Mark: I'm telling you, these interns are out of control.
Callie: Stalkers.
Mark: Sexed-up stalkers.

Mark: We're going to need a strategy. Their hot little eyes tracking our every move.
Callie: Okay. No casual glances over the shoulder. No "this is interesting, come and have a see."

Mark: We did good work today.
Callie: If we stay strong...
Mark: Don't get drunk...
Callie: Keep staring at Joe, we'll be fine.

Mark: Did she, uh, she say goodbye to you?
Callie: No.
Mark: You okay?
Callie: Do I look okay?
Mark: You look great.
Callie: Then I'm okay.

Cristina: Wait, so are you a lesbian now?
Mark: I dunno... maybe you were a "once-bian."
Callie: Or a twice-bian. Whatever. It's over.
Cristina: Are you okay?
Mark: She's fine. Leave her alone.

Callie: We had a fight.
Cristina: Please. Meredith and I fight all the time. We still work together. It's not like Hahn was your girlfriend or something. [long pause] Oh my God. She was your girlfriend?
Callie: We hadn't figured it all out.

Grey's Anatomy Quotes

Just because we can live without something, it doesn't mean we have to.

Meredith

Derek: I am calling post-it, Zola, Bailey, the tumors on the wall, ferryboat scrub caps. I thought D.C. was everything. I was wrong. You... you're everything. I love you and I'm not going to stop loving you. I can't live without you. I don't want to live without you, and I'm going to do everything in my power to prove it.
Meredith: I can live without you, but I don't want to. I don't ever want to.
