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 down the road have kidnapped Gordon Brown, Alistair
Darling, David Miliband and Jack Straw.
They're asking for a £10 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?" the
chap replies  "About a gallon."
