A man flying in a hot air ballon realises he is lost. He reduces his altitude, spots a man in the field down below and shouts, "Excuse me, can you tell me where I am?" The bloke replies, "Yes, you're in a hot air balloon, about 30 foot above this field." "You must be a engineer," says the balloonist. "How did you know?" says the man. "Everything you told me is technically correct, but it's of no use to anyone!" says the balloonist. The man below says, "Well, you must be in management." "I am, but how did you know?" says the balloonist. "You don't know where you are, or where you're going, but you expect me to be able to hel;p. You're in the same position you were before we met, but now it's my fault!" says the engineer.
