Doctor Who (1963) Season 17 Episode 6

Duggan: What about the Mona Lisa? You reckon the Count and Countess are out to steal it?
The Doctor: Yes.
Duggan: I don't know about you, but I'm out to stop them.
The Doctor: They're not going to steal it at five o'clock in the afternoon, are they?
Duggan: Why not?
The Doctor: Because the Louvre is still open. Now, while we're here, why don't you and I find out how they're going to steal it and why, hmmm? Or are you just in it for the thumping?
Duggan: I'm in it mainly to protect the interest in the art dealers who have employed me-
The Doctor: I know, I know, but mainly for the thumping.

(Duggan smashes vase over Countess)
Duggan [ after knocking the Countess out with a vase ]: Sorry, milady.
Doctor: I should think so, too.
That was a Ming vase. Second dynasty. Absolutely priceless.

Countess: My dear, you must be a genius.
Count: Well, let's just say I come from a family of geniuses.

(Duggan picks up a chair and prepare to hit Hermann.)
The Doctor: Duggan, what are you doing for heaven's sake? That's a Louis Quinze!

Doctor: Duggan, your job is to stop his men from stealing the Mona Lisa. The other Mona Lisa.

The Doctor: Duggan, why is it that every time I start to talk to someone, you knock them unconscious?

Countess: My dear, I don't think he's as stupid as he seems.
Count: My dear, nobody could be as stupid as he seems.

Doctor: I say, what a wonderful butler! He's so violent!
