This is the first of four stories that Gavin MacLeod appears in for this series, each time playing a different character. His career was soon to take off, playing recurring roles in several popular TV shows of the '60s, '70s, and '80s: most particularly as Happy in McHale's Navy (1962), Murray Slaughter in The Mary Tyler Moore Show (1970), and, perhaps best remembered, as Captain Stubing in The Love Boat (1977).
Perhaps best remembered as Mr. Whipple in the Charmin toilet paper commercials, this is Dick Wilson's only appearance in this series. His character is uncredited, which may account for why he uses his own last name for his character's last name, i.e. Sherriff Wilson.
