A line of dialogue spoken at the start of "Snake Eyes and Sissies" – "Killing is killing whether done for duty, profit or fun" – is a quote taken from an interview with serial killer Richard Ramirez. "My Monkey" contains numerous samples of interviews from Charles Manson; several of its verses are derived from "Mechanical Man", a song from his 1970 album "". Its lyrics are credited simply to "Manson". The song also contains vocals from Robert Pierce, who was six years old at the time of its recording. He was the son of Rambler guitarist Richard Pierce, and was introduced to Marilyn Manson when both bands shared a rehearsal space in Florida.
