DOCTOR: A gentleman at last. Doctor von Wer, at your service.

SERGEANT: Doctor who?

DOCTOR: (sotto) That's what I said.

DOCTOR: Your eyes, man. You suffer from headaches?

PERKINS: No, I don't.

(The Doctor bangs Perkins' head on the desk.)

DOCTOR: No headaches?

PERKINS: Well, er. Ow!

(Another thump.)

DOCTOR: Oh dear. You call me a liar?

PERKINS: Well, no, no, no, no. Me head does ache.

POLLY: You know, those dresses really do suit you, Doctor.

DOCTOR: Oh, you saucy girl.

KIRSTY: You're the very image of my old granny McLaren.

POLLY: You're wonderful, Doctor.

DOCTOR: I know.
