Not a cannibal *joke* exactly, but something real I read in a village magazine a couple of weeks ago and jotted down for an opportunity to arise to post it.
This is apparently what they get up to in remote Suffolk villages:
"LUNCHEON THANKS May I thank Mrs. Mason and her team of ladies who regularly proved an excellent meal for the over 60's every month. I can assure them that they are much enjoyed by all."
