Marcia Rodd, who plays the woman claiming to be the mother of Mike's child, will turn up again in this season's finale, playing cousin Maude's daughter Carol. That episode served as the pilot for Maude (1972), which premiered the following September as its own series. However, Rodd would be replaced by Adrienne Berbeau in the role, as Marcia opted to not be tied down to a weekly series.
In the DVD release of the second season (disc 3), this episode is the second one on the disc, instead of the first one (the actual chronological order of airing)
