(CNN) -- WARNING: Contains strong language In an episode of the cartoon television series South Park -- "Le Petit Tourette" -- one of its characters, Cartman, overhears a child with Tourette's syndrome swearing. Thinking that this is the best excuse ever for being able to swear and be racist without fear of punishment, Cartman proceeds to pretend to have Tourette's. But as the episode progresses what starts out as a funny joke for him soon turns into a Freudian reversal when he can't actually stop saying exactly what is on his mind, leading to him involuntarily reveal that he has touched another boy's penis and has fantasies about one of the girls at school.
