A joke

My friend George, who moves large space craft around in the sky above us, sent me this joke:

A woman in a hot air balloon realized she was lost. She lowered her altitude and spotted a man hiking on a trail below her.

She shouted to him, "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am."

The man consulted his portable GPS and replied, "You're in a hot air balloon approximately 30 feet above a ground elevation of2346 feet above sea level. You are 31 degrees, 14.97 minutes north latitudeand 100 degrees, 49.09 minutes west longitude.

She rolled her eyes and said, "You must be aRepublican.""I am," replied the man. "How did you know?""Well," answered the balloonist, "everything youtold me istechnically correct, but I have no idea what to make of your information, and I'm still lost. Frankly, you've not been much help to me."

The man smiled and responded, "You must be aDemocrat."

"I am," replied the balloonist. "How did youknow?"

"Well," said the man, " You don't know where you are or where you're going. You've risen to where you are due to a large quantityof hot air. You made a promise that you have no idea how to keep, and you expect me to solve your problem. You're in exactly the sameposition you were in before we met, but somehow now, it's my fault."
