Five cannibals(Man eaters) get appointed as programmers in an IT company.
During the welcoming ceremony the boss says: "You're all part of our team
now. You can earn good money here, and you can go to the company canteen
for something to eat. So don't trouble the other employees". The cannibals
promise not to trouble the other employees.
Four weeks later the boss returns and says: "You're all working very hard,
and I'm very satisfied with all of you. One of our developers has
disappeared however. Do any of you know what happened to her?" The
cannibals disown all knowledge of the missing developer.
After the boss has left, the leader of the cannibals says to the others:
"Which of you idiots ate the developer?"
One of the cannibals raises his hand hesitantly, to which the leader of the
cannibals says: "You FOOL! For four weeks we've been eating team leaders,
managers, and project managers and no-one has noticed anything, and now
YOU ate one developer and it got noticed. So hereafter please don't eat a person who is working.
