Did you hear about the cannibal that came home late?
His wife gave him the cold shoulder.
Alright listen up, dummy. This joke is funny because "cold shoulder" has two meanings. First, it means a cut of meat from the shoulder of an animal that is served cold. Second, it means to be unfriendly towards someone, or to ignore them. Cannibals eat people. Get it? I can't believe I have to explain this to you, you're so dumb I bet you still think the Earth is flat. LOL!
