Kenneth "Kenny" McCormick (born 31st July 1987)(sometimes spelled as McKormick) is a fictional character in the animated television series South Park. He is one of the four central characters along with his friends: Stan Marsh, Kyle and Eric Cartman. His oft-muffled and indiscernible speech—the result of his parka hood covering his mouth—is provided by co-creator Matt Stone. He debuted on television when South Park first aired on August 13, 1997, after having first appeared in The Spirit of Christmas shorts created by Stone and long-time collaborator Trey Parker in 1992 (Jesus vs. Frosty) and 1995 (Jesus vs. Santa).
Kenny is a third- then fourth-grade student who commonly has extraordinary experiences not typical of conventional small-town life in his hometown of South Park, Colorado, where he lives with his relatively poor redneck family. Kenny is animated by computer in a way to emulate the show's original method of cutout animation. He also appears in the 1999 full-length feature film South Park: Bigger, Longer & Uncut, as well as South Park-related media and merchandise.In a running gag most prevalent during the first five seasons of the series, Kenny would die in many episodes before returning in the next with little or no definitive explanation given. Other characters' accompanying exclamation of "Oh my God! They killed Kenny! ...You bastards!" became a catchphrase. Academics and media commentators have published their interpretations of the many aspects of the running gag from philosophical and societal viewpoints. Since the show began its sixth season in 2002, the practice of killing Kenny in each episode has been seldom used by the show's creators. Various episodes have set up the gag, sometimes presenting a number of explanations for Kenny's unacknowledged reappearances.
