A man was flying in a hot air balloon and realized he was lost. He reduced height and spotted a man down below. He lowered the balloon further and shouted, "Excuse me, can you tell me where I am?"
The man below said, "Yes, you're in a hot air balloon, hovering 30 feet above this field."
"You must be an engineer," replied the balloonist.
"I am," said the man. "How did you know?"
"Well," the balloonist said, "everything you have told me is technically correct, but it's of absolutely no use to me."
The man below said, "You must be in management."
"I am," replied the balloonist, "but how did you know?"
"Well," said the man, "you don't know where you are, or where you're going; you're in the same position you were in before we met, but now it's my fault."
