With this final episode, Eddie Albert (Oliver) and Eva Gabor (Lisa) are the only two actors to appear in every episode of the series. Tom Lester (Eb) is the runner-up, appearing in 149 of the 170 episodes.
This was a pilot for a proposed series. Oliver & Lisa only appear in the very beginning to introduce a whole new set of cast members set in California. Oliver does appear several times throughout the episode, via telephone, talking to Carol.
This was a pilot for a loosely connected spinoff of Green Acres. It was based in California and followed the adventures of a kooky secretary and her over-domineering boss, a la The Lucy Show. It never got off the ground as this was the time CBS canceled Green Acres and all other rural based series. The network sought a younger and more urban audience and brought in edgier shows such as All in the Family.
