The boys were doing something odd with the Master Mind game.
Mom: "What are you doing?"
Juss: "Nothing. Just watching an evil demon lose against Orville."
Orville: "No actually, it's an evil master mind from outer space."
Juss: "You think that if he were a master mind, he would be good at Master Mind."
Orville nods: "The world was saved by a game of Master Mind."
