Leo Fuchs, one of the leading lights of America's Yiddish-theater movement, guest stars in this episode as Fedor, the Hungarian uncle of Lisa Douglas. Arriving at the Douglas farm, a nervous Uncle Fedor informs Lisa and Oliver that he is being pursued by sinister secret agents. Oliver doesn't believe a word of it, but before long everyone in Hooterville has gone spy-happy. Len Lesser, who later played the irascible Uncle Leo on Seinfeld, is here cast as the obligatory "mysterious stranger."
