QI, Series Four [D]

[Stephen answering the question on how to create the impression that you've cleaned the house when you haven't.]

Stephen Fry:
You spray or apply furniture polish to a radiator, and it fills the room with the smell of furniture polish. These hints are either from a book called Trade Secrets by Katherine Lapworth and Alexandra Fraser, or from Superhints by the Lady...

Jo Brand:
I know those two. They're slags, the pair of them.

Stephen Fry:
What do you know of the book called Superhints by the Lady Wardington?

Jo Brand:
Yeah, I know her.

Stephen Fry:
Do you know the Lady Wardington?

Jo Brand:
She's a bitch.
