Jackie: Why won't you tell me where you've been?
The Doctor: Actually, it's my fault. I sort of, uh, employed Rose as my companion.
Policeman: When you say companion, is this a sexual relationship?
The Doctor: No!
Jackie: Then what is it? Because you, you waltz in here all charm and smiles and the next thing I know she vanishes off the face of the earth. How old are you then? 40, 45? What, did you find her on the Internet? Did you go online and pretend you're a doctor?
The Doctor: I am a doctor.
Jackie: Prove it - stitch this, mate!
(slaps The Doctor across the face)
