The Huxtable household is turned upside down in the fifth season of the Emmy-winning hit series. As Theo (Malcolm-Jamal Warner) heads off to college, Denise (Lisa Bonet) decides to drop out. Sondra (Sabrina Le Beauf) has twins, making proud grandparents of Cliff (Bill Cosby) and Clair (Phylicia Rashad). Ahmad Rashad and Debbie Allen (Phylicia's then-husband and sister, respectively) guest star this season, as do Naomi Campbell and Plácido Domingo.
