A man was sitting in traffic when a cop knocked on his window.

He rolled down the window and asked the officer: "Why is there such a traffic jam?"

Officer: "A group of terrorists kidnapped a few politicians and are blocking the road. They have threatened to burn the politicians alive in 1000 gallons of gasoline if they don't get a 5 million dollar ransom within the hour. I'm going from car to car collecting donations and would like to know if you'd please help."

Man: "Ok. How much are other people giving?"

Officer: "On average, about two gallons."
