A flying saucer landed by a gas station on a lonely New Mexican road.
The gas station attendant was stunned, but remained calm. On the side of the space craft were the letters “UFO.” As the little green men emerged from the ship, he cautiously approached them.
“Does that stand for Unidentified Flying Object?” he asked with wonder.
“No,” one of the aliens responded, “It stands for Unleaded Fuel Only.”
