A story about two men on a train:
One man says "Whatís that package up there in the baggage rack?" and the other answers "Oh, thatís a McGuffin." The first one asks "whatís a McGuffin?" to which the other replies "itís a device for capturing lions in the Scottish Highlands." The first man replies "but there are no lions in the Scottish Highlands!" and in response hears "well, then thatís no McGuffin."
