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 all 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!
