Young Reinette: Monsieur, be careful! The Doctor: It's just a nightmare, Reinette, don't worry, everyone has nightmares. Even monsters under the bed have nightmares! Young Reinette: What do monsters have nightmares about? The Doctor: Me!

I like that Helen Mirren has been saying the next doctor should be a woman. I would like to go on record and say that the Queen should be played by a man!

Rose: Look at you, beaming away like you're Father Christmas! The Doctor: Who says I'm not, red-bicycle-when-you-were-twelve? Rose: [shocked] What? The Doctor: And everybody lives, Rose! Everybody lives! I need more days like this! Go on, ask me anything; I'm on fire!

Demons run when a good man goes to war. Night will fall and drown the sun when a good man goes to war. Friendship dies and true love lies. Night will fall and the dark will rise when a good man goes to war. Demons run but count the cost; the battle's won but the child is lost.

I stole your childhood and now I’ve led you by the hand to your death. But the worst thing is, I knew. I knew this would happen. This is what always happens. Forget your faith in me. I took you with me because I was vain. Because I wanted to be adored. Look at you. Glorious Pond, the girl who waited for me. I’m not a hero. I really am just a mad man in a box. And it’s time we saw each other as we really are. Amy Williams, it’s time to stop waiting.

The Doctor: Don't blink. Don't even blink. Blink and you're dead. Don't turn your back. Don't look away. And don't blink.

I know this is going to sound very self-serving, and I apologize for it, but if you can write comedy, you can pretty much write anything, because it's the hardest. It's the most technically demanding, the most precisely evaluated form of writing. People know if it works or not. There's a big button marked 'fail,' and that's when nobody laughs.
