Fourth Doctor quotes from Doctor Who

His scarf killed Stimson.

Arrest the scarf then.

Ten thousand years. Cretins. Morons. Half-wits.

Yes, they've not been very clever, have they, unlike us.

They probably won't even hit Tigella.

Well, if my calculations are correct, they certainly won't.

Your calculations?

I inverted your control setting. If he starts the countdown, he'll destroy himself, as well as you and me and, well, the whole planet, of course.

There is power here such as you have never dreamed of. Can you not feel it?

No.

Others follow.

Others?

Believe nothing they say. They're not Biroc's kind.

What are you?

A shadow of my past and of your future.

Adric

Will Romana be all right?

All right? She'll be superb!

If I'm not back in thirteen and a half minutes, dematerialize.

Adric

Without you?!

Romana II

I am not letting you go out there alone!

That's an order. It's time you started accepting orders.

Romana II

It's long past time but how are you going to find it?

With my eyes

Romana II

Adric and I have seen it

Right. Come on then.

Adric

I'm coming too

Romana II

You are not, it's long past time you obeyed order. Now stay here, and if we're not back in thirteen and a half minutes, I want you to dematerialize. Is that understood?

I like that. You're improving.

Adric

I don't see what the law of probability has to do with it.

No. [realizing what Adric said] What?! Adric, I've given you a privileged insight into the mystery of time, yes?

Adric

Yes.

Introduced you to adventures beyond imagining, yes?

Adric

Yes.

And you criticise my logic?

Adric

No, no, I'm just saying that a lot of the time you don't really make sense.

[pauses] Ah! Ah, you've noticed that, have you? Well, anybody can make sense.

Traken Union, famous for its harmony. A whole empire held together by- by people being terribly nice to each other.

Adric

Well, that makes a change.

[about the Keeper disappearing] What do you make of it?

Adric

I don't know. But I do hope we know what we're doing.

Yes, so do I. [realizing what Adric just said] We?!

Adric

[points at the Doctor] You. [the Doctor smiles]

What can't be cured must be endured.

Adric

That's the silliest thing I ever heard.

Oh don't listen to me. I never do.

It's the end... but the moment has been prepared for... [points to a ghostly figure that walks forward]

Adric

The Watcher!

Nyssa

He was the Doctor all the time.

Who are you?

I am...Spartacus.

And so am I.

Mr. and Mrs. Spartacus?

Oh, no-no-no-no-no, we're not married.

Oh, brother and sister? Yes, of course, you look very much alike.

[together] Really?!

The square root of pi is 1.772453850905516027298167483341 - wow!

Roast beef. Bananas. The Medusa Cascade. BANG! [rapidfire] Rose Tyler, Martha Jones, Donna Noble, TARDIS! Shamble-bobble-dibble-dooble. Oh, Doctor, you're so handsome. Yes, I am, thank you.
