The four boys repeatedly witness the rest of South Park Elementary collectively break into song, in the spirit of the musical films.
Although Mr. Gueermo is shown to be abusive to his family (though only capable of light, effeminate slaps) Bridon eventually stands up for himself (punching his father in the face), and joins the team.
"Elementary School Musical" was one of dozens of South Park episodes developed the Thursday before broadcast during a writer's meeting.
[2] High School Musical 3: Senior Year had opened in theaters several weeks before and was a national hot topic; the team had previously mentioned the series as a target for satire.
The initial idea the episode was based on was that everyone in South Park is singing High School Musical-style numbers, except for the four main boys.
[3] This is particularly evident in the episode's final moments, in which the audience never sees the boys preparing their musical number, but are surprised with it at the end.
[3] Stone noted that the children depicted in South Park are fourth graders, the target audience for the Disney films.
[3] Parker and Stone both admitted their favorite part of the episode were scenes in which Bridon Gueermo's father commands the lead, as they found his character, with his slapping abuse, very amusing.
The sets included brief audio commentaries by Parker and Stone for each episode, a collection of deleted scenes, and two special mini-features, The Making of 'Major Boobage and Six Days to South Park.
