Marlo Thomas' siblings, Terre and Tony appear in this episode along with their father, Danny Thomas. Terre and Tony's characters' last name is Cassaneti. The Thomas' mother, Rose Marie's maiden name was Cassaniti.
Sam Denoff, who partnered with Bill Persky to create the series, has a bit part as the Foreign Legion soldier who collapses while Ann is filming the Pop commercial.
Bill Persky, who wrote the script (as well as being producer and series creator), chose St. Thomas to be the name for the orphanage where Sr. Rose works as a shout-out to all the Thomas family members who appear.
Marlo Thomas calls her real father "Father" because he's dressed as a priest. Her real brother and sister have parts in this episode too.
