A driver is stuck in a traffic jam on the highway. Suddenly a man knocks on his window. The driver rolls down his window and asks, "What's going on?"

"Terrorists down the road have kidnapped George W. Bush and Dick Cheney," the man says, "They're asking $100 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?"

The man responds: "Most people are giving about a gallon."
