DOCTOR: What are you doing down here?

ORGANON: A small matter of a slight error in a prophecy.

DOCTOR: Ah. Well, I guess it could happen to anybody.

ORGANON: Why, are you in the business yourself, sir?

DOCTOR: What?

ORGANON: Seeing into the future?

DOCTOR: Oh, well.

ORGANON: Crystal ball man, are you? Or do you favour goat entrails?

DOCTOR: No, I tend to use a police box affair.
