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 the window and asks, "What is going on?" He replies, "Terrorists have kidnapped Congress, and are demanding $10 million dollar ransom. Otherwise, they are going to douse them all in gasoline and set them on fire. We are going from car to car, taking up a collection."
"How much is everyone giving, on average?" the driver asks.
The man relied, "About a gallon." And all I had was a book of matches!
