04x01 - Cartman's Silly Hate Crime 2000

The boys are challenged to a sled race against the girls. When Token says the reason that they’ll win will be due to Cartman’s fat ass, Cartman throws a rock at him and gets into trouble. Then the FBI begins an investigation into his “hate crime,” which gets him put on trial and to make an example out of him he is sentenced to juvenile hall until he reaches the age of twenty-one.
