“Why can't you just say 'don't breathe the water' like a normal person?""Because I'm a doctor, and they teach us never to use little words where big ones will do.”

“Now... Just run.' [said the Doctor.]One of the things you learn very quickly around the Doctor is never to question him when he says that word. You just run. It's almost like breathing.”

“Never use a big word when a little filthy one will do.”

“The Doctor: This is bad, I don't like this. [kicks console and yells in pain] Never use force, you just embarrass yourself. Unless you're cross, in which case... always use force! Amy: Shall I run and get the manual? The Doctor: I threw it in a supernova. Amy: You threw the manual in a supernova? Why? The Doctor: Because I disagreed with it! Now stop talking to me when I'm cross!”

“Why would John bother using windows or doors like a normal person? Why would he bother to say hello? Just poof. Crunch. Bye.”

“A lot of people don't like the road, but it's as natural to me as breathing. I do it because I'm driven to do it, and I either hate it or love it. I'm mortified to be on the stage, but then again, it's the only place where I'm happy. It's the only place you can be who you want to be. You can't be who you want to be in daily life. I don't care who you are, you're going to be disappointed in daily life. But the cure-all for all that is to get on the stage, and that's why performers do it. But in saying that, I don't want to put on the mask of celebrity. I'd rather just do my work and see it as a trade.”
