Scott Malkinson is a minor character in South Park best known for his lisp and diabetes, which other characters make fun of him for. He is described as the least popular kid in the school in "Elementary School Musical", and a few seasons later began to appear regularly as one of the boys' classmates.
Scott wears a light green jacket with a fairly dark green collar and has teal trousers or blue jeans. He also has freckles and ruffled brown hair with a parting in the middle.
