[narrating] We like to think that we are rational beings; humane, conscientious, civilized, thoughtful. But when things fall apart, even just a little, it becomes clear we are not better than animals. We have opposable thumbs, we think, we walk erect, we speak, we dream, but deep down we are still routing around in the primordial ooze; biting, clawing, scratching out an existence in the cold, dark world like the rest of the tree-toads and sloths.

Meredith

[narrating] There’s a little animal in all of us and maybe that’s something to celebrate. Our animal instinct is what makes us seek comfort, warmth, a pack to run with. We may feel caged, we may feel trapped, but still as humans we can find ways to feel free. We are each other’s keepers, we are the guardians of our own humanity and even though there’s a beast inside all of us, what sets us apart from the animals is that we can think, feel, dream and love. And against all odds, against all instinct, we evolve.

Meredith

(to Miranda) Okay, in L.A., people say things, but in Seattle, there's this strange culture of wordlessness, where in I am supposed to guess what one is feeling by the slight raise of an eyebrow or the beginnings of a frown. Any chance you want to tell me what's going on with you, Miranda?

Addison

Mark: There she is.
Addison: Just coming in to check on my patient's skin flap.
Mark: Well, amazing, right? I pulled a couple of stem cells from the baby in utero. Six weeks later, I have grown skin. Like God.
Addison: Nice.
Mark: What do you say we lock that door and tear one off for old time's sake?

Meredith: (narrating) Great surgeons aren't made. They're born. It takes gestation, incubation, sacrifice. A lot of sacrifice. But after all the blood and guts and gooey stuff is washed away, that surgeon you become: totally worth it.

Meredith: (narrating) Giving birth may be all intense and magical and stuff, but the act itself: it's not exactly pleasant. But it's also a beginning... of something incredible. Something new. Something unpredictable. Something true. Something worth loving. Something worth missing. Something that will change your life... forever.

Bet you're wishing you took the stairs right about now...

Mark

Meredith: Hey, you're leaving already?
Addison: I have a plane to catch...I walk on the beach now, I buy aromatherapy candles, I'm very Zen, but I want to kick your ass so badly right now it is killing me.
Meredith: Excuse me?
Addison: I'm talking about Derek. Derek Christopher Shepherd. Are you letting him get away? Because I swear to God Meredith, if you let him ride off into the sunset with that doe-eyed little thing...

You know, whenever anyone says something really funny and I laugh I always look around to see if you think it's funny too. Even when you are not there, I look around.

George

I like penis. I'm a huge huge fan of penis.

Callie

Now may I recommend you all go home? You smell, you're greasy, you need to bathe and I'm sick of lookin' at ya.

Miranda

Callie: Did anyone ever think you two were a couple?
Meredith: No, because we screw boys like whores on tequila.
Cristina: Then we either try to marry them or drown ourselves.
Callie: Huh.

Grey's Anatomy Season 4 Quotes

I tell you that I love you, and not one word? For 17 days? Where have you been?

Izzie

[narrating] In the practice of medicine, change is inevitable. New surgical techniques are created, procedures are updated, levels of expertise increase. Innovation is everything, nothing remains the same for long. We either adapt to change, or ... we get left behind.
