Geronimo!

You don't want to take over the universe. You wouldn't know what to do with it beyond shout at it.

Angel Bob: Doctor? Excuse me, hello, Doctor? Angel Bob here, sir.
The Doctor: Ah, there you are, Angel Bob. How's life? Sorry, bad subject.
Angel Bob: The Angels are wondering what you hope to achieve.
The Doctor: Achieve? We're not achieving anything. We're just hanging, it's nice in here: consoles; comfy chairs; a forest... how's things with you?
Angel Bob: The Angels are feasting, sir. Soon we will be able to absorb enough power to consume this vessel, this world, and all the stars and worlds beyond.
The Doctor: Yeah, but we've got comfy chairs. Did I mention?
Angel Bob: We have no need for comfy chairs.
The Doctor: [amused] I made him say 'comfy chairs'.

There's something that doesn't make sense. Let's go and poke it with a stick.

The Doctor: [aiming gun at the ceiling] Didn't anyone ever tell you? There's one thing you never put in a trap if you're smart. If you value your continued existence, if you have any plans about seeing tomorrow, there's one thing you never, ever put in a trap.
Angel Bob: And what would that be, sir?
The Doctor: Me. [fires]

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!
