In the giant buffet of cartoon characters to choose from, South Park's Chef is the filet mignon next to the Salisbury steak. He is a hilarious, insightful, and totally inappropriate yet caring role model for South Park Elementary's children: notably the show's four young protagonists. When South Park premiered in 1997, Chef became one of its breakout stars and helped fuel its meteoric rise to the heights of pop culture. While The Simpsons were the gold standard for adult cartoons in the '90s, even Springfield's wildest residents were nothing like Chef. He was the wise, cautionary sage who could always be counted on to give the children what they needed most — the truth or something like it — amid the surreal and often shocking humor that served as the show's calling card. If any South Park character could have had a spinoff series, it's Chef.
