Meredith: [voiceover] When you were a kid, it was Halloween candy. You hid it from your parents and you ate it until you got sick. In college, it was the heavy combo of youth, tequila and well, you know. As a surgeon, you take as much of the good as you can get because it doesn't come around nearly as often as it should. 'Cause good things aren't always what they seem. Too much of anything, even love, is not always a good thing.

Meredith: [on the phone, about Burke's house] You're going through his stuff, aren't you?

Cristina: There's no stuff to go through. It's a freak show. I mean, you can do surgery in here. Oh, he arranged his books using the Dewey Decimal system! Mer, I'm scared.

Meredith: Get out, get out of the house—now.

[As Meredith's one night stand runs out of the house]

George: Oh, he's new.

Izzie: I shall name him: "Running Guy."

Meredith: They always look so sad when I kick them out. Seriously, why do guys not understand that when you pick them up in a bar and take them home for sex, that there are no picket fences or kids in your future?

[Cristina takes out the key]

Meredith: Burke keyed you?

Cristina: I got freaking keyed before coffee.

Meredith: What is wrong with them?

Cristina: They're like these 1950s debutantes, one dance and there's a shotgun to your head.

[Meredith's One-Night-Stand walks up]

Steve: Meredith? You work here?

Meredith: What are you doing here...um...Steve?

Steve: I'm having a little problem.

Cristina: Steve, Steve?

Steve: Actually, I'm having a big problem.

[Moves his jacket to reveal his erect penis. Cristina notices and starts staring at it. Meredith doesn't notice.]

Meredith: What?

Cristina: [Still staring] Steve, hi! Cristina.

Steve: Ever since you...and I [Meredith follows Cristina's gaze and does a double-take]...um...it won't go away.

Meredith: Cristina!

Cristina: What? It's right there, looking at me! There are so many things I could say right now — Champ!

Cristina: It's not my fault you broke the guy's penis.

Bailey: Broke his what? [Cristina and Meredith trying to evade her] Hey! Don't make me chase you down. I'm growing a person here!

Cristina: What the hell is this?

Burke: It's a key.

Cristina: Why?

Burke: Why is it a key? Are we feeling existential this morning?

Cristina: Well, if the key turns in a lock, and no one asked for the key or even wanted the key, does it make a sound?

George: Maybe it's a, a matter of v-volume?

Meredith: Volume? What's that supposed to mean?

George: Just, you know there's quality then there's quantity.

Meredith: So you think I'm sleeping with too many guys? You think I'm a slut?

George: I think you're taking some risks. I think you'll find yourself in a hole in some guys basement being ordered to put the lotion on the skin or you'll get the hose again.

Meredith: Oh come on—

George: Excuse me, I'm talking. So you want to be with Derek. You want to be, but you're not. So you try to find some replacement, some temporary way to feel better. But it's not working, and it's not going to work, because the future of meaningless one night stands and problematic penises is not what you want. You want better and you deserve better. And not every guy's a nightmare.

Cristina: Congratulations, you're flaccid.

Patient: Never thought I'd be glad to hear that.

Cristina: Excuse me- what makes you think we can live together? You don't know anything about me.

Burke: I know that you prefer an 11-blade for your IND's, I know you like your coffee from the cart by the front entrance better than the coffee in the cafeteria. I know you.

Cristina: Those are little things, details.

Burke: I know you. You don't want to move. But I can't always be the one that takes the step. Anymore steps and I'm walking away.

Cristina: [to Burke] This is where I live. My mother decorated it. I don't do laundry, I buy new underwear. And uh, the table? Six months of magazines I know I'll never read but I won't throw out. I don't wash dishes, vacuum, or put the toilet paper on the holder. I hired a maid once, she ran away crying. The only things in my fridge are water, vodka, and diet soda, and I don't care. But you do. Still think living together is a good idea?

Meredith: [voiceover] How do you know when how much is too much? Too much too soon. Too much information. Too much fun. Too much love. Too much to ask... And when is it all just too much to bear?
