The group playing (and lip-syncing) their original song, "You," on stage in Adriana's club is the real-life Jersey garage band The Swingin Neckbreakers. One of whose fans is iconic Jersey rocker and "Sopranos" cast member Steven Van Zandt.
The song played during the ending credits is an instrumental remix of "Kid A" by Radiohead.
While Ralphie clips his toenails on the bed, Janice is reading "The Origin of Satan" by Elaine Pagels.
The song Christopher is singing and mocking when he shows up to the construction site is "If I Were a Carpenter." The Bobby Darin version is later used in the episode "Unidentified Black Males."
The episode of "Everybody Loves Raymond" Adriana is watching is "Young Girl."
