Poor taste perhaps but funny
It had been a long, long day, and John the truck driver really wanted to just get home. Living in Washington DC, he knew traffic would be bad this time of evening, but to his horror, a traffic jam reared ahead of him larger than anything he could have anticipated. Bewildered, since he hadn't heard anything yet on the news, he stuck his head out and just kept seeing cars slowing down then driving off. 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 the entire US Congress!"
"Oh my word!" exclaims John.
"And they're asking for a $100 million dollar ransom."
"Oh my!" moans John.
"Otherwise, they are going to douse them all in gasoline and set them on fire!"
"This is terrrible!" cries John.
"We are going from car to car, collecting donations."
"How much is everyone giving, on average?" asks John.
"About a gallon."
