A driver is stuck in a traffic jam. Nothing is moving, when suddenly a man knocks on his window. The driver asked, " What happened?" The man replied, " Terrorists kidnapped Obama. They are asking for a $10 million ransom, or they will douse him with gasoline and set him on fire. We are taking up a collection." The trucker asked, " On average, how much is everyone giving?" The man replied, " About a gallon."
