Cindy Pickett joins the cast as Dr Carol Novino in this episode and continues for the remainder of the series.
On returning to Boston, Dr Fiscus says, "I love that dirty water. Boston, you're my home." This quotes the chorus from the Standells' hit song "Dirty Water", about the Charles River in Boston. Dr Axelrod then says, "The west coast has the sunshine, and the girls all get so tan," quoting the Beach Boys' hit "California Girls" (a cover version of this song was used earlier in the episode during the Venice Beach montage). Both songs were released in 1965.
First time Sagan Lewis is listed in main series cast in opening credits.
