The title of this episode is borrowed from the 1974 psychological thriller starring Gene Hackman specifically in reference to tearing the walls down to look for wiretap bugs.
When Bryan Connerty confronts Lonnie Watley about Watley's investigation, the song playing in in the background is Warren Zevon's "Lawyers, Guns, and Money." The disputed investigation, which showed that Axe and his lawyers paid some cops a great deal of money to quash Danzig's firearms charges, hinges on lawyers, guns, and money.
