A driver was stuck in Washington D.C. in the worst traffic jam he had ever seen... Cars were stretched out for miles ahead of him. As he was sitting there, a young fellow approached his car and knocked on the window. "What's the holdup?", the driver asked. "Well," answered the young fellow, "It seems that a terrorist group is holding the entire U.S. Congress hostage up ahead a few miles. They claim they're going to douse the whole bunch of them with gasoline and start them on fire unless they get $50 million. I'm just going car to car to try and get some donations." "I'd love to help." said the driver. "How much is everyone else giving?" "About a gallon each."
