He's like fire and ice and rage. He's like the night and the storm in the heart of the sun. He's ancient and forever. He burns at the centre of time and he can see the turn of the universe. And... he's wonderful.
He's completely insane!
That, and a bit magnificent.
He has saved your lives so many times and you never even knew he was there. He never stops. He never stays. He never asks to be thanked.
Hey, I'm the Doctor. I can save the universe using a kettle and some string! And look at me, I'm wearing a vegetable!
