Stars: Trey Parker, Matt Stone

By now, if you're unaware of Trey Parker's and Matt Stone's animated series South Park, that rock from which you crawled out under might still be there, so you'd best head back thataway. Always peppered with seething indictments against politics, pop culture, and other real-life societal issues, the Comedy Central mainstay's humor—pushed forward by the young foursome of Cartman, Kyle, Stan, and Kenny—has provided the television with some of its smartest comedy for the last 15 years.

Consider South Park's availability on Hulu Plus as your chance to join modern times and see why South Park is widely deemed superior to both The Simpsons and Family Guy. Do we agree with that stance? Not quite, but, nonetheless, the show remains a must-watch.
