Irrelevant

Two women are on a transcontinental balloon voyage. Their craft is engulfed in fog, their compass gone awry. Afraid of landing in the ocean, they drift for days. Suddenly, the clouds part to show a sunlit meadow below. As they descend, they see a man walking his dog.

One of the fliers yells to the figure far below, "Where are we?"

The man yells back, "About a half mile from town."

Once again, the balloonists are engulfed in the mist. One flyer says to the other, "He must have been a lawyer."

The other says, "A lawyer! How do you know that?"

The first says, "That's easy. The information he gave us was accurate, concise, and entirely irrelevant."
