Bart (voice of Nancy Cartwright) makes the mistake of trying to protect a batch of cupcakes Lisa (voice of Yeardley Smith) made for her teacher from schoolyard bully and thug in training Nelson (voice of Cartwright). Nelson gives Bart a beating, and promises more of the same; Marge (voice of Julie Kavner) suggests that Bart try to reason with the bully, while Homer (voice of Dan Castellaneta) tells his son that fighting dirty is the only answer. Neither strategy seems to work, so Bart turns to Grampa Simpson (voice of Castellaneta) for advice. With the help of Herman (voice of Harry Shearer), the mildly insane owner of a store specializing in military relics, Bart and Grampa organize his fellow fourth graders into an army and orchestrate an all-out water-balloon war against Nelson and his fellow bullies. "Bart the General" was first aired on February 4, 1990.
