A driver is stuck in a traffic jam on the highway. Nothing is moving. Suddenly a man knocks on the window. The driver rolls down his window and asks, "What happened?"
"Terrorists have kidnapped Hillary Clinton, Ted Kennedy, Jesse Jackson, and Al Sharpton. They are asking for a $10 million ransom. Otherwise they are going to douse them with gasoline and set them on fire. We are going from car to car, taking up a collection."
The driver asks, "How much is everyone giving, on average?"
"About a gallon."
