Sherlock Holmes and Dr. Watson are flying a balloon.

Sherlock Holmes and Dr. Watson are flying a balloon. They climbed above the clouds and lost their way. Finally they landed in an unknown area. Suddenly they saw a man going by.
Holmes: ”Sir, couldn’t you tell us where we are?”
The man thought for a long time and replied: “In a balloon basket.”
Holmes: “Watson, that was a typical programmer.”
Watson: “What makes you think so, Holmes?”
Holmes: “First of all, he took so much time to answer such a simple question. Secondly, his answer was absolutely right. Thirdly, his answer was totally useless.”
