This page is a collection of quotations from the era of the sixth official incarnation of the Doctor from the BBC science fiction television programme Doctor Who, during which the role of the Sixth Doctor was played by Colin Baker. As Doctor Who stories in other media (such as books, audio plays, etc) are the subject of intense debate as regarding their place in the series' overall canon, these quotations are largely taken from episodes broadcast on television.

The Caves of Androzani [21.6]

[After regenerating.]

Peri: Doctor?

The Doctor: You were expecting someone else?

Peri: I- I- I-

The Doctor: That's three "I"s in one breath--makes you sound rather egotistical, young lady.

Peri: What's happened?

The Doctor: Change, my dear. It would seem, not a moment too soon.

The Twin Dilemma [21.7]

The Doctor: Ahhh... a noble brow. Clear gaze. At least it will be given a few hours sleep. A firm mouth. A face beaming with a vast intelligence. My dear child what on Earth are you complaining about? It's the most extraordinary improvement.

---

The Doctor: My last incarnation... oh, I was never happy with that one. It had a sort of feckless "charm" which simply wasn't me!

Attack of the Cybermen [22.1]

The Doctor: Rest is for the weary, sleep is for the dead.

---

Peri: Look Doctor, ever since you regenerated, i-it's as if your memory has been put through the meat grinder. I mean, it's all there, but in a pile of unrelated bits and pieces.

The Doctor: That's a horrible simile.

Peri: It's true, though. In the past couple of days, you've called me Tegan, Zoe, Susan. On one occasion, you even referred to me as Jamie.

Vengeance on Varos [22.2]

The Doctor: It's all right for you, Peri. You've only got one life. You'll age here in the TARDIS and then die. But me, I shall go on regenerating until all my lives are spent.

---

[After two men fall into an acid bath.]

The Doctor: Forgive me if I don't join you.

The Mark of the Rani [22.3]

Peri: Do you mean the TARDIS is malfunctioning again?

The Doctor: Malfunctioning? [pause] Malfunctioning? MALFUNCTIONING!? After all the work I've done on it!?

Peri: Well, I only asked a simple question!

The Doctor: Indeed you did, and it was the wrong question!

---

The Rani:What's [the Master] up to now? It'll be something devious and overcomplicated. He'd get dizzy if he tried to walk in a straight line.

The Two Doctors [22.4]

The Sixth Doctor: What's the use of a good quotation if you can't change it?

---

The Doctor: Small though it is, the human brain can be quite effective when used properly.

Revelation of the Daleks [22.6]

[Davros and the Doctor discuss Davros's scheme of turning the bodies of the dead into processed food.]

Davros: This part of the galaxy is developing quickly. Famine was one of its major problems.

The Doctor: You turned them into food?

Davros: A scheme which has earned me great acclaim.

The Doctor: But did you bother to tell anyone that they might be eating their own relatives?

Davros: Certainly not! That would have created what I believe is termed... "consumer resistance".

---

The Doctor: Ah, I see you have been busy.

Davros: Whereas you have been stupid, Doctor.

The Doctor: Prerogative of a Time Lord.

Season 23 : Trial of a Time Lord

[Note: The entire 23rd season comprises a single story arc, but the individual serials are usually referred to by seperate titles. See Doctor Who story title controversy.]

The Mysterious Planet [23.1]

The Sixth Doctor: Planets come and go. Stars perish. Matter disperses, coalesces, forms into other patterns, other worlds. Nothing can be eternal.

---

Glitz: Whereas yours is a simple case of sociopathy, Dibber, my malaise is much more complex. A deep-rooted maladjustment, my psychiatrist said, brought on by an infantile inability to come to terms with the more pertinent, concrete aspects of life.

Dibber: That sounds more like an insult than a diagnosis, Mr Glitz.

Glitz: You're right there, my lad. Mind you, I had just attempted to kill him.

Mindwarp [23.2]

King Yrcanos: Today, prudence shall be our watchword. Tomorrow, I shall soak the land in blood!

---

Sil: You have blundered, Crozier! You have turned the finest economic mind in the galaxy into a catcher of sea snakes!

Terror of the Vervoids [23.3]

The Sixth Doctor: This is a situation that requires tact and finesse. Fortunately, I am blessed with both.

---

[An alert sounds.]

The Doctor: Quickly, Mel! Press the red button! Get the message on the screen.

[Mel presses the button, but nothing happens.]

The Doctor: Press it! Press it!

Mel: I am!

[The Doctor presses a different button and the message appears.]

Mel: You said red.

The Doctor: Did I? It must be the carrot juice making me colour blind!

The Ultimate Foe [23.4]

The Doctor: In all my travelling throughout the universe I have battled against evil, against power-mad conspirators. I should have stayed here. The oldest civilisation: decadent, degenerate, and rotten to the core. Power-mad conspirators, Daleks, Sontarans, Cybermen, they're still in the nursery compared to us. Ten million years of absolute power. That's what it takes to be really corrupt.

---

[After the Master has revealed the Valeyard is really an evil future incarnation of the Doctor]

The Doctor: Madam, this revelation should halt this trial immediately. Surely even Gallifreyan Law must acknowledge that the same person cannot be both prosecutor and defendant.

The Inquisitor: [Upset at his 'unseemly' outbursts] The single purpose of this trial is to determine the defendant's guilt or otherwise on the basis of the evidence that has been presented. Anything else is for the moment irrelevant!

The Doctor: [utterly speechless] WHAT?!

Time's Champion

[The Doctor speaks his final words]

The Doctor You want me to become a god?
