Doctor: One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine. Goodbye, Susan. Goodbye, my dear.

Jo: Well, what have you got in there anyway – a policeman?

Doctor: Why not step inside and see for yourself?

Jo: I don't believe it! It's bigger inside than out!

Doctor: Yes, that's because the TARDIS is dimensionally transcendental.

Jo: What does that mean?

Doctor: It means that it's bigger inside than out!

Barbara: The Doctor’s curious – that means we stay.

Vicki: You’ve lost a button.

Ian: Hmm? Oh, so I have.

Doctor: Lost a button? Hmm, that’s interesting. Yes, that’s very interesting. Hmm.

Ian: Doctor, why do you always show the greatest interest in the least important things, eh?

Doctor: The least important things sometimes, my dear boy, lead to the greatest discoveries. Like steam, for instance, coming out of a kettle. Yes! I was with him at the time. Er, let’s see now, er, yes what was that fellows name? Erm, erm , erm…

Barbara: James Watt.

Doctor: Mmm? Yes, you know, losing a button could change the future.

There's no point in being grown-up if you can't be childish sometimes.

1st Doctor: But you can't rewrite history! Not one line!

Krail: You must come and live with us.
Polly: But we cannot live with you. You're… you're different. You've got no feelings.
Krail: Feelings? I do not understand that word.
1st Doctor: Emotions. Love, pride, hate, fear. Have you no emotions, sir?

1st Doctor: Oh, so you're my replacements. Huh. A dandy and a clown.

Victoria: You probably can't remember your family.
2nd Doctor: Oh yes, I can when I want to. And that's the point, really. I have to really want to, to bring them back in front of my eyes. The rest of the time they… they sleep in my mind and I forget. And so will you. Oh yes, you will. You'll find there's so much else to think about. To remember. Our lives are different to anybody else's. That's the exciting thing, that nobody in the universe can do what we're doing.

2nd Doctor: Logic, my dear Zoe, merely enables one to be wrong with authority.

3rd Doctor: Do you know, Jo, I sometimes think that military intelligence is a contradiction in terms.
