Harding died Monday at 82. He wrote several speeches for Martin Luther King Jr., including his controversial 1967 speech opposing the war in Vietnam. Harding spoke to Fresh Air in 1988.
As a bomb-detecting dog, Zenit the German shepherd never chased his tail or dug holes. Those are skills he learned after he was adopted by his former professional partner, Cpl. Jose Armenta.
The comic tells Fresh Air that after Season 3, he "aggressively forgot the show existed for a few months." Then he got back to work. Louie is now in its fourth season.
