At the beginning of this episode which aired on April 16, 1964, we see Hazel, George, Dorothy, and Harold getting into their new red Ford Mustang coupe and going out to dinner. This is followed by a special opening credit sequence showing Hazel driving the Mustang out of the driveway, which aired only in this episode. This was a special promotion by Ford, a sponsor of the show, who had introduced the Mustang to the public at the New York World's Fair on the previous day.
Jamie Farr, who played Antonio, would go on to play Corporal Klinger in the TV series "MASH".
