Never ignore a coincidence. Unless you're busy, in which case, always ignore a coincidence.

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

Amy: I never knew you drank wine. Doctor: I'm 1103 I must have drunk it sometime in my life. *takes sip and spits it out in disgust*

I like that Helen Mirren has been saying the next doctor should be a woman. I would like to go on record and say that the Queen should be played by a man!

Never run when you're scared. Rule 7.

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!

The Doctor...is embarrassingly human for an alien.
