This episode represents a little reunion between Frank Cady and John Hoyt. In When Worlds Collide (1951), John Hoyt was wheelchair-bound billionaire industrialist Sydney Stanton and Frank Cady was his abused valet Harold Ferris.
Twelve years later, in this episode of Petticoat Junction, Frank Cady is in his regular role of Sam Drucker and John Hoyt has a guest part as a railroad inspector. There is even a scene where Frank is standing behind a seated John pretending to give him a haircut.
