Nothing can ever be a rule in drama, because then you're saying certain things won't ever happen, and that would be very boring.

I can't see what's wrong about assuming intelligence in your audience and what's bad news about being rewarded for assuming that.

I like naked women! I'm a bloke! I'm supposed to like them! We're born like that. We like naked women as soon as we're pulled out of one... When Man invented fire, he didn't say "Hey, let's cook!" He said: "Great! Now we can see naked bottoms in the dark!"... The story of male achievement through the ages, feeble though it may have been, has been the story of our struggle to get a better look at your bottoms.

The difference between a beautifully made failure and a beautifully made hit is who you've got playing the leads.

I'll be a story in your head. But that's OK. We're all stories, in the end. Just make it a good one, eh? Because it was, you know; it was the best.

So is this how it works Doctor? You never interfere with the affairs of other peoples or planets, unless there are children crying?

You don’t just give up. You don’t just let things happen. You make a stand! You say no! You have the guts to do what’s right, even when everyone else just runs away.
