The show focuses on the Huxtable family, an upper middle-class African-American family, living in a brownstone in Brooklyn Heights, New York, at 10 Stigwood Avenue. The patriarch is Cliff Huxtable, an obstetrician and son of a prominent jazz trombonist. The matriarch is his wife, attorney Clair Huxtable. They have four daughters and one son: Sondra, Denise, Theo, Vanessa, and Rudy. Despite its comedic tone, the show sometimes involves serious subjects, like Theo's experiences dealing with dyslexia, inspired by Cosby's dyslexic son, Ennis. The show also deals with teen pregnancy when Denise's friend, Veronica (Lela Rochon), becomes pregnant.
