Not mine but telling it anyway
A driver is stuck in a traffic jam in downtown Chicago. Nothing is moving. Suddenly a man knocks on his window.
The driver rolls down his window and asks, "What happened, what's the hold up?"
"Terrorists have kidnapped Oprah Winfrey, Rosie O'Donnell, Rod Blagojavich, 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're going from car to car, taking up a collection."
The driver asks, "On average, how much is everyone giving?"
The man says "About a gallon!"
