You should always waste time when you don't have any. Time is not the boss of you. Rule 408.

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

It's the 50th year of Doctor Who and look what's going on! We're up in the sky and under the sea! We're running round the rings of an alien world and then a haunted house. There's new Cybermen, new Ice Warriors and a never before attempted journey to the centre of the TARDIS. And in the finale, the Doctor's greatest secret will at last be revealed! If this wasn't already our most exciting year it would be anyway!

When you're surrounded by friends and exes, there's a whole lot of stuff that starts crawling out. But however serious and traumatic those experiences may be to the participant, to the onlooker they're hilarious.

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... time-y wimey... stuff.

You'll go out of business if you think people are stupid.

We have a plan to top it. And I do think our plan is devastating. We’ve practically reduced our cast to tears telling them the plan … we’re probably more excited that we’ve ever been about Sherlock.
