A driver was stuck in a horrible traffic jam outside the House of Parliament. Suddenly a man knocks on the window. The driver rolls down the window and asks, "What's going on?" - "Terrorists have kidnapped everyone in the House of Commons and they're asking for a hundred million pounds ransom. Otherwise they're gonna douse them all in gasoline and set them on fire. We're going from car to car collecting donations." - "How much is everyone giving on average?", the driver asks. The man replies, "Roughly a gallon".
