Dr. Cristina Yang: This... is where I live. My mother decorated it. I don't do laundry, I buy new underwear. See, and uh, under 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. Uh... 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?
Dr. Cristina Yang: [about the key Burke gave her to his apartment] What the hell is this?
Dr. Preston Burke: It's a key.
Dr. Cristina Yang: Why?

Dr. Derek Shepherd: Mhmm.
Dorie Russell: Wow, look at you two. Everybody must hate you.
Dr. Derek Shepherd: [with Addison] Oh, you have no idea.
[Meredith's one-night-stand from the previous night has showed up at Seattle Grace with an erection that won't go away]
[George enters the stairwell. Going up the stairs, he finds Meredith sitting on the stairs by herself]
Dr. George O'Malley: So, how do you break a guy's penis?
Dr. Meredith Grey: You know about Steve too?
