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?'
'Most people are giving about a gallon.'
