Doctor Who: You want weapons? We're in a library. Books are the best weapon in the world. This room's the greatest arsenal we could have. Arm yourself! (from Tooth and Claw in Season 2)

You are worthy of love and respect. You are beautiful, gifted, and intelligent. Don't let the storm make you forget it.

Wilf: God bless the cactuses! The Doctor: That's cactI. Alien: And that's racist!

I would rather be confused for 10 minutes than bored for 5 seconds.

Anything works, as long as you write it properly.

There's nothing better than a party that turns into a death trap.

There's one tiny little gap in the universe left, just about to close. And it takes a lot of power to send this projection. I'm in orbit around a supernova. I'm burning up a sun just to say good bye.

I am the Bad Wolf. I create myself. I take the words. I scatter them... in time, and space. A message to lead myself here.

I saw the Fall of Troy! World War Five! I was pushing boxes at the Boston Tea Party! Now I'm gonna die in a dungeon.... [disgustedly] in Cardiff!

It is natural to man to regard himself as the final cause of creation.

I could never take the idea of religion very seriously.

It is easy to criticize an author, but difficult to appreciate him.

It's much easier to put yourself out there under the guise of a character. You get a different name, different habits, different words. When I have to just be Nathan, that's when I feel vulnerable.

Her idea of a romantic setting is one that has a diamond in it. If you feel the need to marry a doctor, I suggest a dermatologist. Good hours, free Retin-A.

I'm always reading plays, and when I find something that I really want to do, then I'll make the time to do it.
