"Microsoft's Useless" joke
A helicopter was flying in Seattle when suddenly an electrical malfunction disabled all electronic navigation and communication equipment.
Due to the amount of fog, the pilot could not determine the helicopter's position. He spotted a tall building, flew toward it, circled, and held up a handwritten sign that said "WHERE AM I?" in large letters. People in the tall building quickly responded to the aircraft, drew a large sign, and held it in a building window. Their sign said "YOU ARE IN A HELICOPTER."
The pilot thanked them by smiling and waving, determined the route to SEATAC airport and landed safely. When they were finally on the ground, his co-pilot asked him how he'd done it.
"I knew it had to be the Microsoft building, because they gave me a technically correct but utterly and completely useless answer."
