“They're coming. They're coming for you, but listen, your life could depend on this. Don't blink. Don't even blink. Blink and you're dead. They are fast, faster than you can believe. Don't turn your back, don't look away, and don't blink. Good luck.”

“People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff.”

DOCTOR: Now, first things first. Be honest. How do I look?

ROSE: Umm... different.

DOCTOR: Good different or bad different?

ROSE: Just...different.

DOCTOR: Am I... ginger?

ROSE: No, you're just sort of... brown.

DOCTOR: Aw, I wanted to be ginger! I've never been ginger!

“Well, you could do that. Yeah, you could do that. Of course you could. But why? Look at these people, these human beings. Consider their potential! From the day they arrive on the planet, blinking, step into the sun, there is more to see than can ever be seen, more to do than-- no, hold on. Sorry, that's The Lion King. But the point still stands. Leave them alone!”

DOCTOR: (talking about the TARDIS) I don't know what is wrong with her, she's sort of... queasy, indigestion... like she didn't want to land.

ROSE: (deadpan) Well if you think that's gonna be trouble, we can always get back inside and go somewhere else.

(The Doctor and Rose laugh.)

ELEVENTH DOCTOR: Listen, what you get up to in the privacy of your own regeneration is your business.

TENTH DOCTOR: One of them is a Zygon.

ELEVENTH DOCTOR: Urgh. I'm not judging you.

TENTH DOCTOR: Oooh, lovely.

ELEVENTH DOCTOR: Oooh, lovely.

ELEVENTH DOCTOR: It's a timey-wimey thing.

WAR DOCTOR: Timey what? Timey-wimey?

TENTH DOCTOR: I've no idea where he picks that stuff up.

TENTH DOCTOR: Trenzalore. We need a new destination, because I don't want to go.

ELEVENTH DOCTOR: He always says that.

“So, physics. Physics, eh? Physics. Physics. Physics! Physics. Physics, physics, physics, physics, physics, physics, physics. I hope one of you is getting all this down.”
