Underdog is an American animated television series that debuted October 3, 1964, on the NBC network under the primary sponsorship of General Mills, and continued in syndication until 1973, for a run of 124 episodes.
A spoof of superhero melodramas, the cartoon Underdog has a similar Clark Kent-style character, the ordinary dog Shoeshine Boy. But whenever there is trouble afoot, Shoeshine Boy ducks into a phone booth to don his uniform and become Underdog (his quick change routine usually accompanied by the phone booth's explosion). Always speaking in rhymes, the heroic Underdog must thwart evil plots from the likes of Simon Bar Sinister, Riff Raff, and Overcat.

Theme Song and Opening Credits
Theme by W. Watts Biggers
When criminals in this world appear,
And break the laws that they should fear,
And frighten all who see or hear,
The cry goes up both far and near for
Underdog! Underdog! Underdog! Underdog!
Speed of lightning! Roar of thunder!
Fighting all who rob or plunder!
