Bart and Lisa watch a cartoon called "Transclown-O-Morphs." The main character tells kids to buy their new cereal to survive an emergency. Marge gets annoyed by the commercials and wants the kids to get away from TV. She gets Lisa to make banana bread and Bart to go to Shelbyville with Homer to have bean bag chairs "rebeaned." While driving, they see Martin Prince driving a combine harvester. Bart asks him why he would drive a combine harvester, and Martin says he joined 4-H. Bart joins and learns how to drive a tractor. A 4-H volunteer tells the members about a competition. He says you have to pick a calf and raise it over the summer, and the cattle will be judged at a county fair.
