History of Underdog Day

Originally underdog referred to a shipbuilder who stood in a dark pit that assisted with the sawing of wood planks working with a type of supervisor sawing the boards from above. The underdog was filthy and covered in sawdust, but the overdog received all the credit for the hard work done. The meaning of the name changed in the second part of the nineteenth century to mean “the beaten dog in a battle.” An underdog bet was a wager on the dog most likely to lose. Underdog Day, founded by Peter Moeller in 1976, is a day to appreciate all of life’s unsung heroes.

From Forrest Gump to the Karate Kid, the underdog figure has grown extremely prominent in mainstream culture. The average Joes and Gabby Douglas are now recognized for flipping the status of the underdog. In fiction, prominent underdog winners include Rocky Balboa and William Wallace in “Braveheart,” despite their films’ very poor or plain improbable narratives, both have become cult classics, demonstrating the underdog character’s standing. Indeed, humanity has always supported the underdog. Perhaps there’s something fundamental to the human experience that makes us all feel like we’re gathering the sawdust of life and we fantasize about one day emerging triumphant from this dirty, splintery mess.

It appears that individuals are more likely to relate with flawed underdogs whose exploits frequently go undetected than with the heroes who are constantly lauded and ridiculed. It’s difficult to relate with immaculate, infallible individuals who always know what they’re doing and never make a mistake, for the simple reason that this isn’t how reality works. Because no one is flawless, seeing others depicted as such might make us detest them. And the fact is that without their modest sidekicks, the underdogs, many of those heroes would not be who they are or would not have achieved what they have. Imagine Sherlock Holmes without his sidekick Dr. Watson. Isn’t it a little bit different?
