I heard that joke sort of a different way (from 'The Car Guys' on NPR).
The woman consulted her portable GPS and replied, 'You're in a hot air balloon, approximately 30 feet above a ground elevation of 2346 feet above sea level..'
Then the guy in the balloon said, 'OK. Thank you. Now I know right where I am, that I'm above Redmond, WA.'
The woman said, 'How did you know that?'
The guy said, 'Well, you told me some very accurate information that was technically correct but totally useless so I could tell that you work for customer support at Microsoft."
It was funnier when The Car Guys told it.
