Randy Marsh started "South Park" as a simple geologist. He'd hold this position for many years before seemingly pursuing every other creative endeavor. From becoming a world-renowned chef to singing sensation Lorde, Randy has influenced the world in more ways than one. And this influence extends to his role in the town of South Park itself. Randy is there whenever there's a crisis or people looking for leadership.
In "Make Love, Not Warcraft," Randy plays an integral role in getting the sword to Stan so that they can defeat the troll. In "Red Man's Greed," Randy urges his son to find a cure for SARS. In "Night of the Living Homeless," he leads the other townspeople to get all of the unhoused out of their city. People listen and respect Randy and will seemingly follow him to the end of the Earth. Is this merely because he's a charismatic leader people can rally behind? Or is there someone else pulling the strings, winding up greater machinations for something more sinister?
After all, Randy has been used as a pawn to advance other agendas. In "Mexican Joker," Randy's part of a plot to blow up other home-grown marijuana farms so that he can corner the market. And Randy was responsible for taking out Winnie the Pooh in "Band in China." No matter what political happenings are going on, there's Randy nearby. Maybe there are even multiple Randy clones who can be in several places at once, allowing them to extend the higher power's reach. It's a pretty dark theory, and ultimately, Randy having so many jobs is similar to Homer Simpson getting a new job every week. But it's enough to make you wonder if Dr. Mephesto didn't give up his cloning research so quickly after all.
