On "Lassie", Clyde played the eccentric farmer and nature lover, Cully Wilson, the friend to Timmy Martin, portrayed by child actor Jon Provost, in much the same fashion as Burt Mustin was cast as Gus the fireman for Jerry Mathers in "Leave It to Beaver". In "The Real McCoys", Clyde performed as the foil for another veteran character actor, Walter Brennan. Clyde played friendly, usually sincere neighbor George MacMichael to Brennan's devious "Grandpa Amos McCoy". Madge Blake played Flora, the sister of George McMichael with something of a romantic interest in Amos McCoy. Later, Clyde was cast as Skippy Draper in one episode of another Brennan ABC series, "The Tycoon".
