These are stabs at shows I don’t remember that well, but wasn’t Andy and his girlfriend (was she named Barbara?) on Andy Griffith Show another example, and the 60s show He & She?
Andy and Helen were more of a “hurry up and get it over with” couple. He and She was about a married couple.
Great memory of H&S, though! Considering it only ran for a single season, more than 40 years ago.
