premise: Sabrina Le Beauf (born March 21, 1958) is an American actress best known for her portrayal of Sondra Huxtable on the NBC situation comedy "The Cosby Show". She has voiced the character Norma Bindlebeep on the Nick at Nite animated series "Fatherhood", a show based on Bill Cosby's book of the same name.
hypothesis: The character of Sondra Huxtable was developed for the show Fatherhood with Bill Cosby.
reason: The character Sondra Huxtable was on The Cosby Show, not Fatherhood.  This is challenging because both shows, and this character name, do appear in the text.
