The Security Guard..

[Quoi]

A group of cannibals were employed to work in the NHS on the condition that they refrained from eating people.
After 6 months the security guard suspiciously disappears with just a few scattered bones to mark the expiry of his poor soul.
The cannibals are all sacked on the spot.
Their leader calls them all together and they kill and eat the one who recently feasted on the poor guard.
He then turned to the rest of the group and said 'We have been eating people here for 6 months and not been caught but how many times do I have to tell you - Do NOT eat anyone important - JUST the managers'
