Matt Stone

Matt Stone is an American screenwriter, producer, voice artist, musician and actor, best known for being the co-creator of South Park along with creative partner Trey Parker.
 * "South Park" creators Matt Stone and Trey Parker say their bizarre decision to dress in drag and sashay down the red carpet at the 2000 Oscars was made easy - thanks to LSD. "We took acid and tripped," Stone tells the November issue of FHM. "It seemed like the right day - drop acid and get on the red carpet in a dress." But lest anybody think he's a druggie, Stone adds, "I haven't taken acid since then."
