A driver is stuck in a traffic jam on the motorway. Nothing is moving. Suddenly a man knocks on the window. The driver rolls down his window and asks, "What's going on?" "Terrorists have kidnapped Tony Blair, John Prescott, Gordon Brown and Jack Straw. They're asking for a £310 million ransom. Otherwise they're going to douse them with petrol and set them on fire. We're going from car to car, taking up a collection." The driver asks, "How much is everyone giving, on average?" About a gallon!
