A man is flying in a hot-air balloon when he realizes that he's lost. He vents some air from the balloon to get lower to the ground, to find someone to help him.
After a while, he sees someone down below, walking across the field. He calls out to the man below, "Hey! Can you tell me where I am?"
The man on the ground calls up, "Yeah, you're in a hot-air balloon hovering about a hundred feet above this field."
The balloonist shakes his head and says, "You must be an engineer."
The man on the ground is amazed. "Yeah, that's right! How did you know?"
"Because your answer was technically accurate but in reality useless."
The man on the ground answers, "Oh, yeah? Well, you must be management!"
It's the balloonist's turn to be amazed. "That's right! How did you know?"
The man on the ground answers, "Because you've got no clue as to where you are or where you're going, but you expect me to be able to help you, and you're in exactly the same mess you were before you asked me for help, but now it's my fault!"
