“This was supposed to be yesterday. I was sitting on the Cardiff/London train, supposedly about to write this very column, and realising something quite terrible. My head was entirely empty. A vast echoing void. Bigger on the inside, but with nothing in it. You could drop a pebble in my brain and wait for an hour to hear it land. No actually, you couldn't - that would be aggressive and unhelpful, so keep your damn pebbles to yourself.”

“[The Doctor, Capt. Jack and Rose are cornered by the empty children.]The Doctor: Go to your room! Go to your room! I mean it. I'm very, very angry with you. I'm very, very cross! GO! TO! YOUR! ROOM! [The children lurch away and obey him.] I'm really glad that worked. Those would have been terrible last words.”

“You're guaranteed to be lucky several times in your life-it's what you do with it. Young writers spend all their time worrying, in a way that David Gerrold did not and I did not. How do they get to meet the right people? How do they get to the right parties? If only someone would read my script... Forget all that. All these things are easy and will happen. The way you get your script to the right people is that you put it in an envelope. It's fucking easy. The difficult bit is writing something that is so good people will take a punt on a brand new writer. That's it-you have to write an absolutely terrific script.”

“The Doctor: It's my nose; it has special powers.Nancy: Yeah? That why it's so...?The Doctor: What?Nancy: Nothing.The Doctor: What?Nancy: Nothing. Do your ears have special powers too?”

“You know when sometimes you meet someone so beautiful — and then you actually talk with them, and five minutes later they're as dull as a brick. But then there's other people, and you meet them and you think: "Not bad, they're okay," and then you get to know them, and their face sort of becomes them, like their personality's written all over it; and they just — and they turn into something so beautiful. [Simultaneously, with Older Amy] Rory is the most beautiful man I've ever met.”

“Amy Pond: 'I thought... well, I started to think you were just a madman with a box.'The Doctor: 'Amy Pond, there's something you better understand about me, 'cause it's important and one day your life may depend on it. [He Smiles] I am definitely a madman with a box.”

“The universe is big, its vast and complicated, and ridiculous. And sometimes, very rarely, impossible things just happen and we call them miracles. And that's the theory. Nine hundred years, never seen one yet, but this would do me.”
