Harmon Brothers is the name of the social media ad agency that created the unforgettable Squatty Potty video spot. They've cranked out a number of other ads that also went viral (Poo-Pourri, Purple mattresses, Chatbooks, Lume deodorant), helping propel those businesses into multimillion dollar companies.

To help product companies that are struggling during the downturn, Harmon Brothers has announced they're giving away, sweepstakes-style, a $100,000 video marketing campaign. As long as you've got "a product or service that solves a real problem for real people," you're eligible to apply to their "$100K Poop to Gold Giveaway," as it's called.

Ten semifinalists will be chosen, and the Grand Prize winner gets the free campaign. But the other nine aren't left to hang: They get free coaching and/or a year of free access to the online Harmon Brothers University, where they've distilled their formula for going viral into online lessons.
