“Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.”

“Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.”

“Do you know what thinking is? It’s just a fancy word for changing your mind.”

“Oh, the blossomiest blossom. That's the only sad thing. I want to know what happens next. Right, then. Doctor Whoever-I'm-about-to-be. Tag, you're it.”

DOCTOR: The Daleks have failed! Why don't you finish the job and make the Daleks extinct. Rid the Universe of your filth. Why don't you just die?

DALEK: You would make a good Dalek.

BILL: So, the Time Lords, bit flexible on the whole man-woman thing, then, yeah?

DOCTOR: We're the most civilised civilisation in the universe. We're billions of years beyond your petty human obsession with gender and its associated stereotypes.

BILL: But you still call yourselves Time Lords?

DOCTOR: Yeah. Shut up.

DOCTOR: You know when grown-ups tell you everything's going to be fine and you think they're probably lying to make you feel better?

AMELIA: Yes.

DOCTOR: Everything's going to be fine.

AMY: I'm fine. It's just, there's a whole world in here, just like you said. It's all true. I thought. Well, I started to think that maybe you were just like a madman with a box.

DOCTOR: Amy Pond, there's something you'd better understand about me, because it's important, and one day your life may depend on it. I am definitely a madman with a box.

DOCTOR: You're doing it again.

CLARA: Doing what?

DOCTOR: The smile.

CLARA: Yeah, I'm smiling.

DOCTOR: It's the sad smile. It's a smile but you're sad. It's confusing. It's like two emotions at once. It's like you're malfunctioning.

“Good evening. I'm a Lizard Woman from the Dawn of Time, and this is my wife.”

“And now it's time for one last bow, like all your other selves. Eleven's hour is over now. The clock is striking twelve's.”

“Halt! Sonst werden wir Sie exterminieren! Sie sind jetzt ein Gefangener der Daleks”

METACRISIS DOCTOR: No, no, no, no, no. I'm unique. Never been another like me. Because all that regeneration energy went into the hand. Look at my hand. I love that hand. But then you touched it. Wham! Shush. Instantaneous biological metacrisis. I grew out of you. Still, could be worse.

DONNA: Oi, watch it, spaceman.

METACRISIS DOCTOR: Oi, watch it, Earth girl. Ooo. I sound like you. I sound all, all sort of rough.

DONNA: Oi!

METACRISIS DOCTOR: Oi!

DONNA: Oi!

METACRISIS DOCTOR: Spanners. Shush. I must have picked up a bit of your voice, that's all. Is it? Did I? No. Oh, you are kidding me. No way. One heart. I've only got one heart. This body has got only one heart.

DONNA: What, like you're human?

METACRISIS DOCTOR: Oh, that's disgusting.

DOCTOR: Why are you calling me madam?

YASMIN: Because you're a woman.

DOCTOR: Am I? Does it suit me?

YASMIN: What?

DOCTOR: Oh yeah, I remember. Sorry, half an hour ago I was a white-haired Scotsman.

“Allons - as idiots say - y.”

“Because my dad used to say, dice don't know what the dice did last time. Games don't have a memory. Every game starts from scratch.”

“Now, someone tell me what the hell is going on here?”

“I'm going to get killed by a Christmas tree!”

DOCTOR: My entire understanding of physical space has been transformed! Three-dimensional Euclidean geometry has been torn up, thrown in the air and snogged to death! My grasp of the universal constants of physical reality has been changed forever!

DOCTOR: Sorry. I've always wanted to see that done properly.

“Okay. Name - the Doctor. Occupation - not a doctor. Current status - just passing by. Employer - myself. Address - that blue box over there. Now, if you don't mind, I just got snowmanned, and I would like to go home.”

DOCTOR: What the hell are you doing?!

RUBY: I'm... just... There's...

DOCTOR: But what did you do that for? Who sees a ladder and just pops on? A ladder in the sky and you thought, "Yeah, I'll give that a go, babes"?

RUBY: They've got the baby!
