The song references William Shakespeare's Henry VI, Part II: "Old Billy was right: let's kill all the lawyers - kill 'em tonight", echoing Shakespeare's line "The first thing we do, let's kill all the lawyers".
ウィリアム・シェイクスピアの『ヘンリー六世 第2部』を参考にしており、「Old Billy was right: let's kill all the lawyers - kill 'em tonight」は、シェイクスピアの「The first thing we do, let's kill all the lawyers」にあたる。
