President Hoover was mentioned in a few Rowlf the Dog scenes on The Jimmy Dean Show. In one appearance (November 21, 1963), Rowlf writes a love letter to Lassie, requesting she send an autograph picture, which he claims will sit next to his picture of Hoover. In a later sketch (January 16, 1964), Rowlf takes up jazz. When Jimmy Dean suggests he himself play some jazz on the show, Rowlf quips, "Jimmy Dean in a hip combo? Is Herbert Hoover in the Rat Pack?"
