Subject: stuck in a traffic jam
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 Stephen Harper, Stephane Dion & Jack Layton.
They're asking for a $10 million ransom. Otherwise they're going to douse them with gasoline 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 4 litres.'
