A big 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 the other employees".

     The cannibals promised they would not.  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 rose hesitantly, to which the leader of the cannibals
     Continued,

     "You fool!  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!!! "
