According to the DVD supplementals: Billy Joel was inspired to write a fun song while watching "Moonlighting"; the song he created was "Big Man on Mulberry Street". He then offered the song to the show's producers; this episode was specifically written to use the song as a song-and-dance dream sequence centerpiece.
The "Big Man on Mulberry Street" production number was directed by veteran musical director Stanley Donen.
Rick Ducommon, who appears in this episode, would go on to have small parts in two future Bruce Willis films. Die Hard (1988) and The Last Boy Scout (1991)
