- Carl Hoffmeyer: You see, Henri, you and Jules are in this business to make money. I am not. I *have* money. My pleasure, my only desire, is to own art treasures money can NOT buy.
- Carl Hoffmeyer: [proceeds to show them some of these art treasures, hidden behind a secret wall]
- Jules: I don't understand. What pleasure do you get out of it?
- Carl Hoffmeyer: Well, I suppose you'll think I'm crazy, but, you see, to sit quietly all alone at night, in front of treasures - which rightfully belong to the world at large - the only one allowed to admire their unsurpassed beauty, to know that I am the secret owner of a collection that even kings or maharajahs COULD NOT BUY!... THAT is the only satisfaction I get out of life. And I won't rest until I have the 'Mona Lisa.'
- Sam Todworthy: Well, well, well. If it isn't Mr. Hoffmeyer. I thought today you'd show up.
- Carl Hoffmeyer: Why?
- Sam Todworthy: Oh, I put two an' two together.
- Carl Hoffmeyer: And what did it add up to?
- Sam Todworthy: Oh, a jolly sight more'n four, if you know what I mean, *and* I think you do.
- Inspector Bob Cartwright: Do you mind if I examine *your* stick, Mr. Hoffmeyer?
- Carl Hoffmeyer: And what if I *do* mind?
- Inspector Bob Cartwright: I'm afraid I shall have to insist.
- Carl Hoffmeyer: In that case, help yourself.
- Tony Collison: What about grandpa?
- Inspector Bob Cartwright: Look, what he doesn't know won't hurt him. We'll pull this thing off yet. Chin up, darling.
- Tony Collison: Chin up my foot!
