Charles Dickens: How exactly are you a "fan"? In what way do you resemble a means of keeping oneself cool?

Doctor: No, it means fanatic, devoted to you... Mind you, that American bit in Martin Chuzzlewit, what's that about? Was that just padding or what? It's rubbish that bit.

Charles Dickens: I thought you were my fan?

Doctor: Oh, well, if you can't take criticism... Do the death of Little Nell. It cracks me up.
