With its 20th season ready to knock us all on our butts, what is South Park’s secret to staying relevant and funny after all these years and all these seasons? The gross out humor? The socially relevant topics? A liberal mix of both those things with the ability to cross the decency line time and time again and yet still make it all look effortless?

Well, I’ll never tell the secret South Park formula (Just kidding. it’s Butters. He injects some purity into the show and makes the show magical, but that is just my personal opinion), but Looper have a pretty good idea of what makes South Park work so well, too. Peep their theory in the video above.
