Five cannibals are appointed as programmers at an IT company.They're at work for six weeks when the boss comes in and says: "You're all working very hard, and I am satisfied with all of you. However, one of our janitors has disappeared. Do any of you know what might have happened to her?"
The cannibals disavow all knowledge of the missing janitor.
After the boss has left, the leader of the cannibals says to the others: "OK. Which of you idiots ate the janitor?"
A hand raises hesitantly, to which the leader of the cannibals says: "You bloody idiot! For four weeks, we've been eating Team Leaders, Managers, and Project Managers so no-one would notice anything, and you have to go and eat a janitor!"
