Brock Samson's devotion to Led Zeppelin surfaces in several episodes. Some references are subtle - when driving the Charger, Brock almost always is listening to facsimile Led Zeppelin songs - while others are more overt, such as Hank rifling through Brock's collection of "Zep" cassette tapes, or Brock drawing the logo of the band's label instead of completing the essay portion of a written exam. He even has a (currently incomplete) tattoo of the label on his arm.
