Growing up in the 1980s, the two were creating comic books, filming Super 8 movies and eventually toying with a video camera.
Matt is the primary voice actor of the site Homestar Runner. He currently works as a writer and director for the children's television series Yo Gabba Gabba!, as well as for the Disney Channel animated series Gravity Falls and The Hub live-action series The Aquabats! Super Show!, where he also contributes occasional voice work and supporting acting roles. Most notably on The Aquabats! Super Show!, he played the main antagonist of the season one episode "CobraMan!", playing a sleazy carnival barker named Carl, whose voice and appearance were modeled directly after Strong Bad. Matt wrote the Wander Over Yonder episodes "The Bounty" and "The Timebomb" in collaboration with the show's writing staff.
Mike is responsible for half of the Adobe Flash animation, the technical aspects of a site, and provides intentionally-poor imitations of his brother's voice work for the Powered by The Cheat cartoon series. He has also served as a writer for Yo Gabba Gabba!, and like his brother Matt has collaborated with the Wander Over Yonder staff, credited for writing the episode "The Liar".
