Man: Burglar! Burglar!
Woman: Yes?
Man: Burglar, madam.
Woman: What do you want?
Man: I want to come in and steal a few things, madam.
Woman: Are you an encyclopedia salesman?
Man: No, madam, I'm a burglar. I burgle people.
Woman: I think you're an encyclopedia salesman.
Man: Oh, I'm not. Open the door - let me in, please.
Woman: If I let you in, you'll sell me encyclopedias.
Man: I won't madam. I just want to come in - ransack the flat. Honestly!
Woman: Promise? No encyclopedias?
Man: None at all.
Woman: All right, you'd better come in then.
Man: Mind you, I don't know whether you've ever really considered the advantages of owning a really fine set of modern encyclopedias. You know, they can do you really wonders.
