The Doctor: Rose... before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? [Pause] So was I!

*Throwing bread out of door* AND STAY OUT!

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!

Rose Tyler: Can't you come through properly? The Doctor: Then the whole thing would fracture. The two universes would collapse. Rose Tyler: So?

Harriet Jones: Did you notice when they fart, if you'll pardon the word, it doesn't just smell like a fart, if you'll pardon the word, it's something else. What is it? It's more like, um... Rose Tyler: Bad breath. Harriet Jones: That's it! The Doctor: Calcium decay. Now that Narrows it down!.. Calcium phosphate. Organic calcium. Living calcium. Creatures made out of living calcium. What else - what else? Hyphenated surnames. Yes! That narrows it down to one planet! Raxacoricofallapatorius! Mickey Smith: [sarcastically] Oh yeah, great! We can write 'em a letter.

Rose: My mum's here. The Doctor: Oh, that's just what I need! Don't you dare make this place domestic! Mickey Smith: You ruined my life, Doctor. [the Doctor turns and looks at him, irritated] They thought she was dead, I was a murder suspect because of you! The Doctor: [looks at Rose] See what I mean? Domestic! Mickey: I bet you don't even remember my name! The Doctor: Ricky. Mickey: It's Mickey! The Doctor: No, it's Ricky. Mickey: I think I know my own name! The Doctor: You think you know your own name? How stupid are you?

Maybe that's when bad scripts are written, when you choose the theme first. I consider that I've something to say when I've thought of a person, a moment, a single beat of the heart, that I think is true and interesting, and therefore should be seen.
