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 approximately 124 episodes.
Underdog, Shoeshine Boy's heroic alter-ego, appeared whenever love interest Sweet Polly Purebred was being victimized by such villains as Simon Bar Sinister or Riff Raff. Underdog always speaks in rhymes, such as, "There's no need to fear, Underdog is here!"
When he is not Underdog, he is incognito as a shoeshine boy. Like Superman, when trouble calls, he hurriedly dresses in a phone booth (which would inexplicably explode upon his conversion). In order to release his powers, he must take an "Underdog Super Energy Pill". The "Underdog Energy Vitamin Pill" was first introduced in Episode 10. He keeps one of these pills inside a special ring he wears at all times. (Before taking one, he would often utter the words: "The secret compartment in my ring I fill / with an Underdog Energy Vitamin Pill".) Several episodes show Underdog losing the ring and being powerless, since he must take another pill as his super powers begin to fail ("Without my Super Energy Pill / I grow weaker and weaker and weaker still"). When the series was syndicated in the 1980s and 1990s, the scenes of him taking his energy pill were edited out.
