You wait til he leaves the house. Take all of his food in the house and get rid of it. Break his PS4/whatever. Make a trail with the pieces, going from the front door to his bedroom. When he gets home and sees it, he will follow it. Be in his bed with his best friend. When he starts to scream, tell him that you just wanted to experience something bigger than his little inchworm. Get dressed and go outside. Key his car/truck. Leave.
