"Microsoft and Helicopters" joke
A helicopter flying above Seattle encountered an electrical malfunction which disabled all of its electronic navigation and communications equipment. The pilot was unable to determine his position and course to proceed to the airport due to heavy clouds and haze.
Seeing a tall building, he flew toward it, circled, and drew a handwritten sign which he held up to the window. His sign read, "WHERE AM I?" in very large letters.
Those in the tall building saw his sign and quickly responded with an even larger sign of their own, which read, "YOU'RE IN A HELIOPTER." The pilot smiled and waved at them, looked at his map again, determined the course to steer and fortunately, landed safely.
Finally on the ground, the co-pilot asked the pilot how the "YOU ARE IN A HELICOPTER" sign helped to determine their position.
"I saw the sign and knew that had to be the Microsoft building because, just like their help-lines, they gave me a technically correct but completely useless answer."
