Schoolhouse Rock! is a 1973 series of animated musical educational short films that aired during ABC's Saturday morning children's block. The topics that these shorts covered included grammar, science, economics, math, and history. Original vocal artist Jack Sheldon provides the music in "Mr. Griffin Goes to Washington".
In "Mr. Griffin Goes to Washington", The Bill appears singing "They Call Me Bill", a parody of the song "I'm Just a Bill", that ends with him being picked up like trash.
In "Running Mates", "Vagina Junction" parodies "Conjunction Junction".
Peter expresses "It’s great to learn, ’cause knowledge is power!" from Schoolhouse Rock! in "Brian Wallows and Peter's Swallows".
While trying to join a skinhead gang for his safety in "Shanksgiving", Peter tries to psych himself up to shiv Cleveland by blaming him for the Schoolhouse Rock! Bill becoming a law.
