Terror of the Autons:
Unnamed Time Lord: You are incorrigibly meddlesome, Doctor, but we've always felt that your hearts are in the right places.
The Android Invasion:
Sarah Jane: I feel disoriented.
The Doctor: This is the Disorientation Centre.
Sarah Jane: Makes sense.
The Doctor Dances:
Rose: Doesn't the universe implode or something if you dance?
The Doctor: Well, I've got the moves, but I don't want to boast.
The Time Meddler:
The Doctor: What do you think of that now, eh? A Viking helmet.

Camera Obscura, by Lloyd Rose:
Anji Kapoor: Why does he wear that coat?
Fitz Kreiner: He once said it was in a spirit of irony.
Anji: Hah! He's just ashamed to admit he thinks it's cool. And he should be. It's embarrassing.
Fitz: It's just a coat Anj.
Anji: And that name! "Sabbath". Like a comic-book villain. He probably thought that sounded cool too. I'll bet his real name is Melvin or something. He's so full of himself. He's like ... like ... Wile E. Coyote, Super Genius! (pg. 158).

The Doctor: I make my own luck.

[referring to the Nestene Conciousness's control of plastic]
The Doctor: Think of it. Plastic - all over the world - every artificial thing, waiting to come alive. Shop window dummies, phones, the wires, the cables ...
Rose: The breast implants ...
The Eight Doctors by Terrence Dicks
Unnamed Time Lord: This particular emergency appears to concern the Doctor.
President Flavia: Yes, they usually do!
The Time Meddler:
The Doctor: That is the dematerializing control, and that over yonder is the horizontal hold; up there is the scanner, those are the doors, and that is a chair with a panda on it. Sheer poetry dear boy. Now please stop bothering me.
Time and the Rani:
Ikona: You must be the Doctor. I've met your companion, Mel.
The Doctor: Don't hold that against me.
State of Decay:
The Doctor: Funny about the windows.
Romana: What windows?
The Doctor: Yes ...
Ian: I have a friend who specializes in trouble. He dives in and usualy finds a way.
