A driver was stuck in a traffic jam on the highway outside Washington , DC . Nothing was moving. Suddenly, a man knocks on the window.

The driver rolls down the window and asks, "What's going on?"

"Terrorists have kidnapped Congress, and they're asking for a $100 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, collecting donations."

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

The man replies, about a gallon each

Count me in for ten gallons.

I am in for a gallon or twenty.

I'll fill a 55 gallon drum with Super Premium. Just tell me where to have it delivered.
