Kenneth "Kenny" McCormick is a fictional character and one of the four main protagonists in the adult animated sitcom South Park, alongside Stan Marsh, Kyle Broflovski, and Eric Cartman. His often muffled and incomprehensible speech—the result of his parka hood covering his mouth—is provided by co-creator Matt Stone. After early appearances in The Spirit of Christmas shorts in 1992 and 1995, Kenny appeared in South Park television episodes beginning August 13, 1997, as well as the 1999 feature film South Park: Bigger, Longer & Uncut, where his uncovered face and voice were first revealed.
