Featured music in this episode: Huey Lewis and the News' "It's Hip to be Square;" and "Macarena."
Roger's 1996 persona of Dr. Ya Ya tries to catch Elián González when the Smiths arrive, but the Elián González affair didn't occur until 1999-2000.
Stan and Francine travel back to 1996 to find the identity of the man who may he Hayley's father, which would make Hayley only 16 years old in the present. However, it has been established that Hayley is in community college, making her at least 18, and more than likely she is over 21 since we see her (in this very episode) out drinking with her mother.
