 The third segment , “ Wiz Kids ” , was written by Carolyn Omine . Omine stated in the DVD audio commentary for the episode that the segment was “ a really hard sell ” , since only about four of the writers had read Harry Potter and the Philosopher ’ s Stone , the book the segment was based on , while the rest of the writers did not know about the book and thought viewers would not know who Harry Potter was . At the time of the episode ’ s production , four books had been written in the Harry Potter series and the film adaptation of Harry Potter and the Philosopher 's Stone would be released November 16 , ten days after this episode aired . Two scenes were cut from the segment ; one of them would serve as an extension of Montymort and Slithers plotting their scheme , followed by a scene showing Bart combing his hair , while the other scene would show Groundskeeper Willie riding an enchanted lawn mower . The latter scene was cut for time .
