ROMANA: Oh, I do love the spring. All the leaves, the colours.

DOCTOR: It's October.

ROMANA: I thought that you said we were coming here for May week.

DOCTOR: I did. May week's in June.

ROMANA: I'm confused.

DOCTOR: So was the TARDIS.

ROMANA: Oh, I do love the autumn. All the leaves, the colours.

DOCTOR: Well, at least with something as simple as a punt nothing can go wrong. No coordinates, no dimensional stabilisers, nothing. Just the water, a punt, a strong pair of hands and the pole.

(Whereupon the pole gets stuck in the mud of the riverbed and the Doctor has to let it go. They drift on under a bridge.)

DOCTOR: Blaming the Universe is the only way I can get out of bed in the morning.

DOCTOR: Change, my dear. And it seems not a moment too soon.

DOCTOR: It's the end. But the moment has been prepared for.

MASTER: If we do cooperate, there'll be no question of you ever returning to Gallifrey.

DOCTOR: If we don't cooperate, there'll be no question of Gallifrey.

ROMANA: How did you know?

DOCTOR: Oh, knowing's easy. Everyone does that ad nauseam. I just sort of hope.

DOCTOR: We're all basically primeval slime with ideas above its station.

DOCTOR: First things first?

ROMANA: Exactly.

DOCTOR: But not necessarily in that order.

DOCTOR: One must always accept the unexpected.

DOCTOR: Ha ha! We did it!

K9: Please clarify.

DOCTOR: Well, I just put a lot of spin on the TARDIS, and the asteroid simply sliced us up out of the gravity whirlpool. Oh, you know, K9, sometimes I think I'm wasted just rushing around the universe saving planets from destruction. With a talent like mine, I might have been a great slow bowler.

RIGG: Yes, but who do you work for?

DOCTOR: Work for? I don't work for anybody. I'm just having fun.

DOCTOR: Of course we should interfere. Always do what you’re best at, that’s what I say.

DOCTOR: Well, to be fair, I did have a couple of gadgets which he probably didn't, like a teaspoon and an open mind.

SCARLIONI: Yes, it would. So you stole the bracelet simply because it's pretty?

DOCTOR: Yes. Well, I think it is. Don't you?

SCARLIONI: Yes.

COUNTESS: My dear, I don't think he's as stupid as he seems.

SCARLIONI: My dear, nobody could be as stupid as he seems.

DOCTOR: Oh.

SCARLIONI: This interview is at an end.

DOCTOR: I say, what a wonderful butler. He's so violent.

DAVROS: I have failed!

DOCTOR: Yes. What does it feel like?

DOCTOR: Would you mind not standing on my chest? My hat's on fire.

DOCTOR: Here. Look, how can I explain? Listen, Einstein's Special Theory of Relativity said

EMILIA: Said that you cannot travel in space faster than the speed of light, because the speed of light is a limiting factor. If you travelled more than a hundred and eighty thousand miles per second, you'd encounter the time distortion effect.

DOCTOR: Yes. Yes, well, he was nearly right.

EMILIA: In fact, you'd arrive at your destination before you'd left your starting point.

DOCTOR: Yes. Absurd, isn't it?

EMILIA: Oh, I don't know.

DOCTOR: I always thought it was fun, myself. I did try to explain the realities to poor old Albert, but he would insist that he knew best.

EMILIA: Oh, they're all the same, these physicists. Oh, sorry.

KIMUS: You don't think that's wrong, do you?

DOCTOR: Wrong? It's an economic miracle. Of course it's wrong.

ROMANA: Newton? Who's Newton?

DOCTOR: Old Isaac? Friend of mine on Earth. He discovered gravity. Well, I say he discovered gravity. I had to give him a bit of a prod.

ROMANA: What did you do?

DOCTOR: Climbed up a tree.

ROMANA: And?

DOCTOR: Dropped an apple on his head.

ROMANA: Ah, and so he discovered gravity.

DOCTOR: No, no, he told me to clear off out of his tree. I explained it to him afterwards at dinner.

DOCTOR: Er, excuse me! What I'd like to know. Where did you get those jelly babies?

ROMANA: Same place you get them.

DOCTOR: Where?

ROMANA: Your pocket.

DOCTOR: By the time I've called look out, what's your name?

ROMANA: Romanadvoratnelundar.

DOCTOR: By the time I've called that out, you could be dead. I'll call you Romana.

ROMANA: I don't like Romana.

DOCTOR: It's either Romana or Fred.

ROMANA: All right, call me Fred.

DOCTOR: Good. Come on, Romana.

DOCTOR: Have you ever heard of the Flying Dutchman?

LEELA: No.

DOCTOR: Pity, I've often wanted to know who he was.
