"But he had such an honest face."
"Romana, you can't be a successful criminal with a dishonest face."
Romana and the Doctor, in "The Ribos Operation"
"You don't think that's wrong, do you?"
"Wrong? It's an economic miracle. Of course it's wrong."
Kimus and the Doctor, in "The Pirate Planet"
I'll never be cruel to an electron in a particle accelerator again.
The Doctor, in "The Pirate Planet"
He's the one you should be talking to, or rather listening to, if you have the stamina.
Romana describes the Doctor, in "The Pirate Planet"
Doctor, beware; your manner appeals only to the homicidal side of my nature.
The Captain, in "The Pirate Planet"
"I just put 1.795372 and 2.204628 together."
"And what does that mean?"
"Four!"
The Doctor and Romana, in "The Pirate Planet"
What do you want? You don't want to take over the universe, do you? No... you wouldn't know what to do with it, beyond shout at it.
The Doctor, in "The Pirate Planet"
The concept is simply staggering. Pointless, but staggering.
The Doctor, in "The Pirate Planet"
My biorhythms must be at an all-time low.
The Doctor, in "The Pirate Planet"
"A plank?"
"The theory is very simple. You walk along it, at the end you fall off. Drop one thousand feet. Dead."
The Doctor and the Captain, in "The Pirate Planet"
"All guards, alert: someone is using a counterjamming frequency projector. Find it and destroy it immediately."
"I don't suppose any of the guards know what a counterjamming frequency projector looks like."
"Destroy everything!"
The Captain and Mr Fibuli, in "The Pirate Planet"
"I warn you, Doctor; he doesn't like scientists."
"Well, very few people do, in my experience."
Professor Rumford and the Doctor, in "The Stones of Blood"
"I still don't understand about hyperspace."
"Well, who does?"
"I do!"
"Oh, shut up, K9!"
Professor Rumford, the Doctor, and K9 in "The Stones of Blood"
Gosh, that takes me back. Or forward. That's the trouble with time travel; you can never remember.
The Doctor, in "The Androids of Tara"
"What's that? Is it yours?"
"My favorite charger. Strong as a tree and swift as the wind."
"Well, how does it go? What makes it work?"
"Good heavens, I don't know, my dear."
"You don't?"
"I'm a knight, not a farrier."
Romana and Count Grendel, in "The Androids of Tara"
Would you mind not standing on my chest? My hat's on fire.
The Doctor, in "The Androids of Tara"
"A swordsman does not fear death if he dies with honour."
"Then he's an idiot."
Farrah and the Doctor, in "The Androids of Tara"
"Would you let a small band of semi-savages stand in the way of progress?"
"Well, progress is a very flexible word. It can mean just about anything you want it to mean."
Fenner and the Doctor, in "The Power of Kroll"
"Oh, it's a sort of Holy Writ?"
"It's atrociously writ."
Romana and the Doctor, in "The Power of Kroll"
"Why do you always assume the worst?"
"Because it usually happens."
The Doctor and Romana, in "The Armageddon Factor"
"Where's your joy in life? Where's your optimism?"
"It opted out."
The Doctor and Romana, in "The Armageddon Factor"
"Optimism: belief that everything will work out well. Irrational, bordering on insane."
"Oh, do shut up, K9."
K9 and the Doctor, in "The Armageddon Factor"
I'll explain it to you another time, when I've got about two weeks to spare.
Romana, in "The Armageddon Factor"
Your silliness is noted. Drive systems regenerating...
K9, in "The Armageddon Factor"
It is not power that we seek, but destruction that we glory in.
The Shadow, in "The Armageddon Factor"
Did you ever get to Troy, Drax? A little place in Asia Minor...
The Doctor, in "The Armageddon Factor"
Is that all you can say? She was a living being, and now what is she? A component!
Romana, in "The Armageddon Factor"
"Remember me to Gallifrey."
"Bye-bye, Drax..."
Drax and the Doctor, in "The Armageddon Factor"
We have the power to do anything we like. Absolute power over every particle in the universe. Everything that has ever existed or ever will exist, as from this moment. Are you listening to me, Romana? Because if you're not listening, I can make you listen. Because I can do anything. As from this moment there is no such thing as free will in the entire universe -- there is only my will, because I possess the Key to Time.
The Doctor, in "The Armageddon Factor"
"Hence, this new device. It's called a randomizer, and it's fitted to the guidance systems and operates under a very complex scientific principle called pot luck. No one knows where we're going, not even the Black Guardian."
"Not even us."
The Doctor and Romana, in "The Armageddon Factor"
How can a robot catch laryngitis? I mean, what do you need it for?
The Doctor, in "Destiny of the Daleks"
Ooh, look; rocks!
The Doctor, in "Destiny of the Daleks"
Who was it said the living are just the dead on holiday?
The Doctor, in "Destiny of the Daleks"
"Judging by design and size, I'd say it had intergalactic range and time-rip capability."
"Well, without reference to my Jane's Spacecraft of the Universe I wouldn't dispute that."
Romana and the Doctor, in "Destiny of the Daleks"
"They taught me at school how to stop my hearts."
"Hearts? How many have you got?"
"One for casual, one for best."
Romana and Tyson, in "Destiny of the Daleks"
"I have failed!"
"What's it like?"
Davros and the Doctor, in "Destiny of the Daleks"
"There we are: the Louvre. One of the greatest art galleries in the whole galaxy."
"Nonsense; what about the Academia Stellaris on Sirius V?"
The Doctor and Romana, in "City of Death"
One of my funny turns? The whole world took a funny turn...
The Doctor, in "City of Death"
"Einstein says that--"
"I'm not paying Einstein, Professor; I'm paying you."
Professor Kerensky and Scaroth, in "City of Death"
I say, what a wonderful butler; he's so violent!
The Doctor, in "City of Death"
Doctor, the more you try to convince me that you're a fool, the more I'm likely to think otherwise.
The Countess, in "City of Death"
