That's better than some of the "advice" I've gotten from some tech support calls.
Reminds me of this joke.
A student pilot and his instructor were flying around Seattle when an unpredicted storm rolled in. Heavy clouds severely limited visibility. The small plane was not equipped for instrument flying, so VFR (visual flight rules) only. They were hopelessly disoriented and lost. Suddenly, the clouds parted a bit and they saw a high-rise building with someone working by a window. The instructor opened his window and yelled:
"Where are we?"
The guy in the window yelled back:
"In an airplane."
The instructor told the student pilot to make a 120° turn to port and start descending. Soon, SeaTac airport came into view and the tower cleared them for an emergency landing, which they accomplished safely.
The student asked the instructor how he knew what to do. The instructor replied:
"The guy in the window gave us a 100% accurate answer that was 100% useless, so I knew it was the Microsoft HQ building and knew how to get to SeaTac from there."
