This episode has the return of possibly the most (heretofore) one-shot characters in the show: Casey Gant (Jonathan Bennett) from episode 1.9, Drinking the Kool-Aid (2004), Luke Haldeman (Sam Huntington) from episode 1.5, You Think You Know Somebody (2004), Sean Friedrich (Kevin Sheridan) from episode 1.10, An Echolls Family Christmas (2004), Carrie Bishop (Leighton Meester) from episode 1.14, Mars vs. Mars (2005), and Cole (Daniel Bess ) from episode 1.8, Like a Virgin (2004).
In one flashback of Shelly Pomroy's (Melissa Hoover) party, Veronica (Kristen Bell) tells Dick Casablancas (Ryan Hansen), "You have nice hair." According to creator Rob Thomas , Ryan Hansen, who plays Dick Casablancas, got the role over another actor because Thomas said he had "good hair."
Although Shelly Pomroy (Melissa Hoover) is a frequently mentioned character, she is only shown once in the series - in this episode - and has no lines.
This episode was originally called "Up on the Roofie"
The song Veronica (Kristen Bell) or Dick (Ryan Hansen), depending on whether Madison (Amanda Noret) or Casey (Jonathan Bennett) got the story correct, sings along to while drunk at the party, is the 'I Touch Myself' cover from Saucy Monky's 2004 album 'Turbulence'. A song originally performed by Christina Amphlett.
