Underdog is an American animated television series that ran from October 3, 1964, to March 4, 1967 starting on the NBC network until 1966, with the rest of the run on CBS, under the primary sponsorship of General Mills, for a run of 62 episodes. The show continued in syndication until 1973.

Underdog, Shoeshine Boy's heroic alter ego, appears whenever love interest Sweet Polly Purebred is being victimized by such villains as Simon Bar Sinister or Riff Raff. Underdog nearly always speaks in rhyming couplets, as in "There's no need to fear, Underdog is here!" His voice was supplied by Wally Cox.

Characters

Underdog was an anthropomorphic dog superhero. The premise was that "humble and lovable" Shoeshine Boy was in truth the superhero Underdog. George S. Irving narrated and comedy actor Wally Cox provided the voices of both Underdog and Shoeshine Boy. When villains threatened, Shoeshine Boy ducked into a telephone booth, where he transformed into the caped and costumed hero, destroying the booth in the process when his superpowers were activated. Underdog almost always spoke in rhyme:

"When Polly's in trouble (or When help is needed), I am not slow,

It's hip-hip-hip and AWAY I GO!!!"

Underdog's most frequent saying when he appeared was:

"There's no need to fear--

Underdog is here!"

The majority of episodes used a common template as the final scene. A crowd of people looking up into the sky would say, "Look in the sky!" "It's a plane!" "It's a bird!" After this, a woman wearing glasses would exclaim, "It's a frog!" Another onlooker would respond, "A frog?" To this, Underdog replied with these words:

"Not plane, nor bird, nor even frog,

It's just little old me ... [at this point, Underdog would crash into something, then sheepishly finish] "Heh-heh-heh. Underdog."

Underdog usually caused collateral damage. Whenever someone complained about the damage, Underdog replied:

"I am a hero who never fails;

I cannot be bothered with such details."

The villains almost always managed to menace Sweet Polly Purebred (voiced by Norma MacMillan), an anthropomorphic canine TV reporter, as part of their nefarious schemes; she was a helpless damsel in distress most of the time and had a habit of singing, "Oh, where, oh, where has my Underdog gone? Oh, where, oh, where can he be?" She would sing this to the music of the song "Oh Where Has My Little Dog Gone" whenever in jeopardy. Recurring villains included:

Simon Bar Sinister, voiced by Allen Swift, is a mad scientist with a voice reminiscent of Lionel Barrymore.
Riff Raff, also voiced by Allen Swift, is an anthropomorphic wolf gangster based on noted actor George Raft. His right-hand man is Mooch, while other gang members (seen in one episode each) include Sandy the Safecracker, Spinny Wheels (who drives the gang's getaway car), Dinah Mite (the underworld's greatest bomb tosser), Nails the Carpenter, Needles the Tailor, Smitty the Blacksmith, and the Witch Doctor.

Other villains included The Electric Eel (a.k.a. Slippery Eel), Battyman, Tap Tap the Chisler (an evil look-alike of Underdog who does not speak in rhyme), and Overcat. Underdog also regularly faced enemies from alien worlds, such as the Marbleheads from the planet Granite, the Magnet Men of the Magnet Planet, the aliens from the planet Zot, and the Flying Sorcerers of the Saucer Planet.

The majority of the Underdog adventures were presented in the form of four-part serial episodes. Other cartoons, including Go Go Gophers and The Hunter, filled the middle segments. A 1969–1973 NBC run featured all four parts of an Underdog storyline in one half-hour show. The series was first syndicated in the U.S. in the mid-1960s under the title Cartoon Cut-Ups, which presented two Underdog segments along with Tennessee Tuxedo and His Tales and The World of Commander McBragg. This package was revised in the 1970s under the Underdog Show title, now including all 124 Underdog segments and featuring Tennessee Tuxedo, Commander McBragg, Go Go Gophers, and Klondike Kat in various episodes. A syndicated package prepared for distribution outside the United States (which also aired on the Boomerang cable network) usually featured two brief Underdog episodes in a single show along with a wider variety of other Total TV cartoon shorts which appeared between such segments: Go Go Gophers, The King and Odie, Klondike Kat, Tennessee Tuxedo, The Hunter, Tooter Turtle, and Commander McBragg.

On these interstitial cartoons, Tennessee Tuxedo, a penguin, was accompanied by two friends, slow-witted walrus Chumley and Professor Phineas J. Whoopie, "the Man With All The Answers". Tennessee Tuxedo was voiced by Don Adams of Get Smart (and later Inspector Gadget) fame; the knowledgeable Professor Phineas J. Whoopee was voiced by Larry Storch of F Troop fame. With the possible exception of Tennessee Tuxedo, none of these characters ever reached Underdog's level of popularity.

Superpowers

When he is not Underdog, he is incognito as Shoeshine Boy. Like Superman, when trouble calls, he hurriedly dresses in a phone booth (which would inexplicably explode upon his conversion). On occasion, to replenish his powers, he would take an "Underdog Super Energy Pill". This pill was first introduced in episode 9. 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 of my ring I fill / With an Underdog Super Energy Pill.") Several episodes, starting with RiffRaffville, show Underdog without his 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.") and, as a result, he can die; but of course, this being a children's cartoon show, no one actually kills him, even when he is at their mercy. He tells everyone who will listen this "secret" of his super powers. When the series was syndicated in the 1980s and 1990s, the scenes of him taking his energy pill were edited out. In the recent release Underdog: The Ultimate Collection, the word "Energy" was replaced with "Vitamin".

Underdog is shown to have incredible superhuman powers. However, the number and scope of his superpowers are inconsistent from episode to episode, being subject not only to the conventions of superhero comics, but also to the conventions of humorous cartoons. In one episode, he easily moved planets, safely butting against them with his rear end. In another episode, his Super Energy Pill, diluted billions of times when added to a city's water system, was capable of giving normal humans who drank the water enough strength to easily bend thick steel bars. Among his many powers shown on the show are: super strength, super speed, supersonic flight, physical invulnerability, X-ray vision, super breath, cosmic vision, atomic breath, atomizing eyes, heat vision, ultrasonic hearing, a supersonic high-pitch hi-fi voice and a great calculating brain.

Theme song

The show is also remembered for its title song, "Underdog," which was arranged and produced by Robert Weitz, with lyrics by Chester Stover, W. Watts Biggers, Treadwell Covington, and Joseph Harris. Several notable covers of the theme song have been made. The original song was sung by Robert Ragaini. He explained, "As a struggling singer in New York, I'd gotten a job singing a theme song for a newly proposed TV cartoon series named 'Underdog." I went to the studio, I think "O.D.O." on West 54th Street, sang as part of the backup group (ah-ooo, ah-ooo), then quickly sang the theme song over the track and left. I remember how pleased I was that I'd taken that mouthful of words and made them understandable. Oh yes, they paid me 50 dollars. No contract - I wasn't yet a member of SAG - and I was thrilled to get it. Until I heard it again, year after year. By then I'd become a successful jingle singer and I knew what I should have been making. When it came out as the music track of a Reebok commercial I filed a claim with the Screen Actors Guild, but of course I had no documentation. A friend did give me an Underdog T-shirt. I wore it once, but when a man I passed on West 14th Street started singing the song, I retired it. -->

The Butthole Surfers released a version included on the 1995 tribute album Saturday Morning: Cartoons' Greatest Hits, produced by Ralph Sall for MCA Records.
Ted Kooshian's Standard Orbit Quartet included the song on their 2009 CD Underdog, And Other Stories... .
An extended a cappella version was done by The Blanks on the TV program Scrubs during the episode titled "My Hero". They later recorded it on their 2004 album Riding the Wave.
The hip-hop music producer and members of the Wu-Tang Clan the RZA sampled "Underdog" theme in their 1993 song titled "Wu-Tang Clan Ain't Nuttin To F' Wit". This song was released in Wu-Tang debut album Enter the Wu-Tang (36 Chambers).
The 'Underdog theme was used in a commercial for Reebok ZQuick shoes in 2014.

DVD releases

On June 14, 1996, Sony Wonder released "Underdog" on VHS in region 1 in a four-volume collection, videocassette set released in the 1990s. On July 24, 2007, Classic Media released Underdog on DVD in region 1 in a three-volume collection, following a previous three-volume set released in the late 1990s. Each volume features six digitally remastered and uncut, original broadcast episodes, each featuring two Underdog segments alongside additional cartoons from the Total TV library.

On February 21, 2012, Shout! Factory (under license from Classic Media) released a 9-disc Complete Series set containing new bonus material, including commentaries. According to Shout! Factory, "they're rebuilding the shows to their original television airing as best as they can".

Film adaptation

In 2005, Variety reported that a live-action Underdog motion picture was in development. As announced, the story introduces "a diminutive hound named Shoeshine [who] gets superpowers after a lab accident. When he's adopted by a 15-year-old boy, the two form a bond around the shared knowledge that Shoeshine is really Underdog." Actor Peter Dinklage was cast to play Simon Bar Sinister, while Alex Neuberger was cast to play Underdog's human companion, Jack Unger. The movie started filming in Providence, Rhode Island, in March 2006 and was released on August 3, 2007. The film was distributed by Walt Disney Studios Motion Pictures. Shoeshine/Underdog, voiced by Jason Lee, was played by a golden beagle named Leo sporting a red sweater and a blue cape. The film got mostly negative reviews, despite grossing $65.3 million worldwide.

Radio

In 1999, Biggers created a new episode of Underdog as a half-hour radio show narrated by veteran Boston newsman Tom Ellis with new original music composed by Biggers. Radio stations were asked to participate in Biggers' Victory Over Violence organization by airing the adventure in which the evil Simon Bar Sinister develops a Switchpitch baseball to turn positive people negative. His attempt to become king of Boston is foiled by Underdog (played by Biggers) and Sweet Polly Purebred (portrayed by Nancy Purbeck).
