Bart and his pals are holding nothing back! First, the sons of The Legitimate Businessman's Social Club (aka the Mafia) take over Springfield Elementary, and they have their sights set on recruiting Bart as their newest member. And when Lisa applies her study habits to the art of pranking, she gives Bart a healthy dose of competition for the title of "Class Clown." Then, Bartman tangles with an eight-baby-wielding villain named Dr. Octuplets. Also, Martin Prince makes a move up the social ladder, Homer offers Maggie the moon, and Principal Skinner resorts to desperate measures to contain the force that is Bart Simpson!
