BRIGADIER: Yes. You know, just once I'd like to meet an alien menace that wasn't immune to bullets.

DOCTOR: I had to face my fear… That was more important than just going on living.

DOCTOR: A straight line may be the shortest distance between two points, but it is by no means the most interesting.

DOCTOR: Courage isn’t just a matter of not being frightened, you know. It’s being afraid and doing what you have to do anyway.

DOCTOR: That's calmed her down a bit. She's very temperamental when she's roused, isn't she.

JO: You know, I never know whether you're joking or not, I, Ow. Oh, I think I've bruised my tailbone.

DOCTOR: Sorry about your coccyx, Jo, but these little things are sent to try us.

JO: My what?

DOCTOR: Coccyx. Your tailbone.

MASTER [on scanner]: I'm sorry about your coccyx too, Miss Grant. How very sociable of you both to drop in.

DOCTOR: All right, all right, I suppose you want to see my pass? Yes, well, I haven't got one. And I'm not going to tell you my name, either. Now you just tell Brigadier Lethbridge-Stewart that I want to see him. Well, don't just stand there arguing with me, man! Get on with it!

DOCTOR: I hate computers and refuse to be bullied by them!

JAMIE: Doctor, come on, will ye? The whole place is going to blow up.

DOCTOR: Oh, it's quite all right, Jamie. The planet is quite safe. There's just going to be a localised volcanic eruption. It'll only affect the island.

JAMIE: Maybe so, but we happen to be on the island.

DOCTOR: Oh, my word!

DOCTOR: Our lives are different to anybody else’s. That’s the exciting thing. There’s nobody in the universe can do what we’re doing.

DOCTOR: You look very nice in that dress, Victoria.

VICTORIA: Thank you. Don't you think it's a bit--

DOCTOR: A bit short? Oh, I shouldn't worry about that. Look at Jamie's.
