 After Principal Skinner makes a chauvinistic remark towards a former female student, an uproar ensues, prompting for his demotion. Subsequently, Melanie Upfoot (Frances McDormand) is appointed the new principal of Springfield Elementary, whom divides the school into two, one for boys, and the other for girls. Frustrated with how the boys in her school are being educated more so than the girls, Lisa disguises herself as a boy to expand her knowledge, and as a result, wins the Student Achievement Award.
