A man is driving his car when he's trapped in a traffic jam. Suddenly, someone is knocking at his window. He lowers the window and asks:

"What's up?"

"Terrorists have kidnapped President Bush! They're demanding 10 million dollars, otherwise they will soak him with gasoline and set him on fire!"

"Holy crap!" responds the man in the car.

"Yeah, I know!" the other man responds. "we're going from car to car, collecting for him."

"How much are people donating, on average?"

"Oh... about five gallons."
