When Hodgins starts talking about a dancer he once knew named Abby Rhoades, Booth calls him Ringo and tells him to stop talking. This is a reference to The Beatles, as their penultimate album was "Abbey Road", and Ringo Starr was their drummer.
Second (and final) appearance of Jessica Capshaw as Rebecca Stinson, Agent Booth's (David Boreanaz) ex girlfriend and mother of their son Parker (who does not appear in this episode). Capshaw and Boreanaz previously starred in the movie Valentine (2001) together. Although Parker is a recurring character throughout the series, Rebecca only appears on-screen in one other episode, Mother and Child in the Bay (2006).
