This is the second episode in a row with a classic rock reference. Last episode played "Karn Evil 9" by ELP. In this episode, Noah says "Won't Get Fooled Again," referencing The Who song of the same name. The episode title, Let it Bleed" is the name of a Rolling Stones song and album from 1969. Drugs, anger, danger and seediness are themes of both the song and the album; an album that was remarked on for its slightly surreal and threatening nature, which is somewhat reminiscent of the carnival theme of this season.
