In "Cartman Finds Love", Nichole and her family are eating dinner when her father brings up that Nichole has a boyfriend, Token Black. Although he is happy for her, he subtly teases her for gravitating to the only other African American student at South Park Elementary. Nichole's mother interjects by finding nothing wrong with that, and encouraging Nichole.
