Cultural references.
Music by Australian horrorcore rap artist KidCrusher is featured in the episode, including the songs "Killin' Shit" and "A Dirty Fuckin' Murder". The artist said he was told the episode was based on a horrorcore festival when he allowed his music to be featured in "Steel-Eyed Death". Upon learning the episode depicted Juggalos, he later claimed to be angry that his music was used. He said, "I am pretty pissed off to hear they based the episode on Juggalos and try to make us all look like criminals and real serial killers, and that we would kill kids."
This episode is partially inspired by the Richard Alden Samuel McCroskey III case. McCroskey, an amateur horrorcore rapper who was heavily inspired by horrorcore rap artist Mars and went by the name "Syko Sam", was accused of murdering four people in Farmville, Virginia. The victims were a Presbyterian pastor, his estranged wife, their teenage daughter (who had been dating McCroskey), and one of their daughter's friends.
Reception.
