Plot summary
Craig annoys the family while living with them. The boys buy a used moped and fix it up, only to have Lois confiscate it. Reese takes the bike out anyway and ends up breaking his leg. Malcolm tricks Craig into believing he ran over Reese. Even though Lois eventually finds out the truth, she does not punish them because it got Craig to leave. Hal visits Francis at the academy's father/son day and is disappointed to learn that Francis is still a troublemaker. He is later proud when Francis stands up for his friends to an unfair Spangler.
