A driver is stuck in a traffic jam on the M11.

Nothing is moving. Suddenly a man knocks on the window.

The driver rolls down his window and asks, "What happened?"

"Terrorists have kidnapped Tony Blair, Cherie Blair, Gordon Brown, John Prescott and Peter Mandelson. They are asking for a £10 million ransom. Otherwise they are going to douse them with petrol and set them on fire. We are going from car to car, taking up a collection."

The driver asks, "How much is everyone giving, on average?"

"About a gallon."
