A Luke joke is a joke that's so bad nobody but the person telling the joke laughs. A Luke joke is also usually followed by stares of disbelief at the joke-teller's complete lack of humor.
Person 1: "So you know what killed the dinosaurs?"

Person 2: "A Meteor?"

Person 1: "No. DinoSARS! (laughing uncontrollably)"

Person 2: "You're a retard. Stop telling Luke jokes."
