When one of Bart's pranks goes to far, Groundskeeper Willie loses his job and is replaced by a state of the art custodial robot. Then, Bart and Gil team-up in the Springfield Elementary cafeteria for a lesson in lunch specials. And to top it off, Lisa takes it upon herself to restore the joy and promise of the teaching profession to Miss Hoover, when the second-grade teacher not only loses her edge but finds herself precipitously close to going over it.
