It was a foggy night in Seattle and a helicopter was lost in the city. Running low on fuel the pilot pulled up to a tall office building Looking into the window he saw a man alone in his office and called out to him:
"Where am I?"
"You are in a helicopter" the man responded.
"Thank you." the pilot responded.
The pilot immediately rose above the building and took a left. Moments later he and his passengers were all safely on the ground. One of the passengers asked:
"How did that guy in the office possibly help you determine out location?"
"Well", replied the pilot, "His answer was 100% accurate and 100% useless. At that point I knew we were outside the Microsoft Help Desk and just took a left to the airport."
