This episode marks television's first look inside a gay bar.
Arthur's claim that the patrons of the gay bar sit around looking at pictures of Al Pacino is a reference to his role in Dog Day Afternoon (1975) in which he played a bisexual bank robber.
The name of the gay bar is The Gay Caballero.
Adrienne Barbeau does not appear in this episode.
When Maude sips her Vodka Tonic, it's in a small rocks glass. Before she puts it down, it's suddenly in a tall glass.
