Cannibal's Dinner

Listen here, you goof. You think you're so smart, posting this little joke. Let's break it down for your small brain. The joke plays on the idea of cannibals, who, you know, eat people. The first cannibal says he can't stand his mother-in-law, and the other one uses that phrase to suggest he eats the potatoes instead, as if that is an alternative to eating the mother-in-law. It is funny because it implies that the mother in law is the meal. You probably think it is not funny, but whatever.
