What do you call a cannibal who devours his mother in law?
Gladiator!
Seriously, this is true: Fijian cannibals killed and ate an Anglican missionary, the Rev. Thomas Baker. They had never seen leather boots before, and boiled his for hours in an attempt to tenderize them.
To this day in Fiji, “Go eat the boots of Mr. Baker!” is considered a deadly insult, implying backwardness and savagery.
That's neat.
