South Park exploded on the pop culture landscape like a dirty bomb in 1997, and all the episodes that comprise the groundbreaking first season have lost none of their subversive impact. If Seinfeld was a show about nothing, then South Park is a show about everything, from important moral lessons in compassion and tolerance to good old-fashioned animated character assassination (Kathie Lee Gifford in "Weight Gain 4000" and Barbra Streisand in "Mecha-Streisand"). Like an After School Special gone quite mad, profanity-spewing third-graders Stan, Kyle, Cartman, and the ill-fated Kenny navigate childhood in their mountain town. Nothing in South Park is sacred, and each episode has something to offend, from "Big Gay Al's Big Gay Boat Ride" (featuring George Clooney as the voice of Sparky, the homosexual dog), to the Halloween episode "Pink Eye," in which Cartman dresses up as Adolph Hitler. Best not to even get started on Mr. Hankey, the Christmas Pooh, or the season finale cliffhanger, "Cartman's Mom Is a Dirty Slut."
