may as well bash the contractors also:

A man is flying in a hot air balloon and realizes he is lost.

He reduces height and spots a man down below. He lowers the balloon further
and shouts: "Excuse me, can you help me? I promised my friend I would meet
him half an hour ago, but I don't know where I am"

The man below says: "Yes, you're in a hot air balloon, hovering 30 feet
above this field at 40.55 deg. North latitude and 120.28 deg. West
longitude"

"You must be an Architect," says the balloonist. "I am" replies the man."How
did you know?" "Well" says the balloonist, "everything you have told me is
technically correct, but it's of absolutely no use to me and I still don't
know where I am."

The man below says, "You must be a contractor.""Well yes" replies the
balloonist, "but how did you know?"

"Well", says the man, "You don't know where you are, or where you're going
and you've made a promise that you can't keep but now you expect me to solve
your problem; and you're in the same position as you were before we met, but
now it's my fault.
