"Why don’t cannibals eat clowns? Because they taste funny!” This popular cannibal-eats-clown joke (wordplay on “tastes funny” meaning “strange” or “not right” and “tastes funny” meaning “ha-ha") dates to at least 1991.
“Two clowns are eating a cannibal” is a jocular backwards variation of this joke.
