The TV news guys were flying in their chopper when fog closed in below them. There electronics failed them so they had no idea where they were. They saw a tall building sticking above the fog, so they went close and held up a sign, "Where are we?" Someone in an office held up the reply, "You are in a helicopter." When the pilot read the reply, he headed right to the airport and landed. The reporter asked him how he knew where to go. The pilot said, "The answer was technically correct, but completely useless for our problem, so I knew it had to be the Microsoft office and once I knew that, I knew where the airport was."
