Several cannibals were recently hired by a big corporation. “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 the other employees”. The cannibals
promised. Four weeks later their boss remarked, “You're all working very
hard and I'm satisfied with you. 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 boss had left, the leader of the cannibals said to the others,
“Which one of you idiots ate the secretary?” A hand raised hesitantly, to
which the leader of the cannibals continued, “You fool! For four weeks
we've been eating Managers and no one noticed anything, then you had to go and
eat a secretary!”
