Suddenly, a man knocks on the window. The driver rolls down the window and asks, "What’s going on?"
"Terrorists have kidnapped Congress, and are asking for a $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 replies, "About a gallon."
