In the scene where Jeff and Wayne are going through their yearbook, Jeff reads a quote from the school's lunch lady who's name is Doris Grau. Doris Grau was a script supervisor on "The Simpsons" who also provided the voice of "Lunch Lady Doris".
Dear Wayne, you are a little brat. I hope you die over summer vacation.
Wayne Foxworthy: Man that was one angry lunch lady.
