The "guy" in question is revealed to have a very active online habit, including posting to Television Without Pity.com. In real life, Gregory Thomas Garcia (creator of My Name Is Earl (2005)) had been posting in the forums at TWoP as this character months before the show aired, and in fact posted his line the night before the episode aired. The following day Joy and Crabman made posts under his user-name WhoJackie.
In the scene where Randy is wearing headphones and singing along with the radio, the song in question is "High School Never Ends" by Bowling for Soup; off their 2006 album: The Great Burrito Extortion Case.
