A huge corporation recently hired several cannibals.
"You are all part of our team now", said the HR rep during the welcoming briefing. "You get all the usual benefits and you can go to the cafeteria for something to eat, but please don't eat any of our employees."
The cannibals promised they would not.
Four weeks later the HR rep called them together and remarked, "You're all working very hard and we're satisfied with your work. However, one of our secretaries has disappeared. Do any of you know what happened to her?"
The cannibals all shook their heads 'No.' After the HR rep had left the room, the leader of the cannibals said to the others, "OK - which one of you idiots ate the secretary?"
A hand rose hesitantly.
"You fool!" the leader continued. "For four weeks we've been eating managers, and no one noticed anything. But NOOOooo, you had to go and eat someone who actually does something!!!"
