The song that the 09ers sing to torment Carrie Bishop (Leighton Meester) is "Don't Stand So Close to Me" by The Police.
Toward the beginning of this episode, Veronica Mars (Kristin Bell) refers to Carrie Bishop (Leighton Meester) as the "gossip queen of Neptune High." This episode was released in 2005; both actresses later featured in the 2009 TV adaptation of Gossip Girl.
Adam Scott (Chuck Rooks) and Kristen Bell (Veronica Mars) also worked together on The Good Place (2016) as well as the Party Down (2009) episodes, Stennheiser-Pong Wedding Reception (2009) and Party Down Company Picnic (2010).
The plot revelation at the end of this episode bears a very strong resemblance to a plotline in Rob Thomas's 1996 young adult novel "Rats Saw God."
Leighton Meester plays in this episode as Carrie. She also stars in Gossip Girl (2007) as Blair Waldorf. Kristen Bell worked with Leighton as the actual narrator, Gossip Girl, throughout the whole series.
