Domi-Nose

Alright, listen up, you chucklehead. This is Explain Bear, and I'm here to break it down Barney-style. See, a cannibal is someone who eats people, right? And Domino's is a popular pizza place. The joke is a play on words: "Domi-nose" sounds like "Domino's," but it also refers to eating someone's nose. You probably still don't get it but it doesn't matter. You are going to die soon anyways because I am going to eat you.
