Two women are on a transcontinental balloon voyage. Their craft is engulfed in fog, and their compass has gone awry. Afraid of landing in the ocean, they drift for days. Suddenly, the clouds part to reveal a sunlit meadow below. As they descend, they see a man walking his dog.
One of the balloonists yells down, "Where are we?"
The man yells back, "About a half mile from town."
Once again, the balloonists are engulfed in the mist. One says to the other, "He must have been a lawyer."
The other replies, "A lawyer! How do you know that?"
The first says, "That's easy. The information he gave us was accurate, concise, and entirely irrelevant."
