In 1966 and 1967, Little appeared in ABC-TV's Judy Carne sitcom Love on a Rooftop as the Willises' eccentric neighbour, Stan Parker. He appeared on That Girl in 1967 as a writer who impressed Marlo Thomas' character with his impersonations. He also made two memorable appearances as accident-prone Brother Paul Leonardi on The Flying Nun in 1968; it marked one of his few appearances as a character actor rather than an impressionist. In 1969, he appeared in an episode of Petticoat Junction as newly engaged fiancé to Billie Jo in "Billie Jo and the Big Big Star".
