One day, on a highway outside of Washington DC...

A driver was stuck in a traffic jam on the highway just outside of Washington, DC. Nothing was moving.

Suddenly, a man knocks on the driver’s window.

The driver rolls down the window and asks, “What’s going on?”

“Terrorists have kidnapped the entire US Senate, and they’re asking for a 100 million-dollar ransom. Otherwise, they say they’re going to douse them all in gasoline and set them on fire. We’re going from car to car, collecting donations.”

“How much is everyone giving, on the average?” asks the driver.

The man replies, “About a gallon.”
