A driver is sat in a traffic jam on the motorway when another motorist comes down the queue and knocks on his window.
"What is the hold up" asks the driver
"Terrorists have captured Gordon Brown and Alastair Darling and are demanding a ransom of £10 million or they will douse them in petrol and set light to them. Some of the other motorists have suggested we start a collection, do you want to give?" comes the reply.
"How much are the others contributing?" asks the driver.
"About a gallon each" comes the reply.
