Five cannibals 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 cleaners has
disappeared however. Do any of you
know what happened to her?”

The cannibals disavow all knowledge of
the missing cleaner. After the
boss has left, the leader of the
cannibals says to the others: “Which
of you idiots ate the
cleaner?”

A hand raises hesitantly, to which the leader of the cannibals
says:
“You fool! 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 the cleaner!”
