Kenny McCormick is the fourth member of the South Park main kids and is the quietest of the bunch as his parka covers his mouth. However, if you listen carefully you can hear the extreme potty mouth of his hilarious character. Kenny is from a poor family and has many siblings. The running gag in the first five seasons was Kenny would be killed off each episode, only to be brought back with no explanation. He was eventually killed off in season five for good only to be brough tback in season six. Now they don't kill him so much. It's good cause we like Kenny.
