America's number one-rated series for three years running, The Cosby Show manages to hold on to this lofty status throughout its fifth season on the air. Bill Cosby is of course back as obstetrician Cliff Huxtable, as is Phylicia Rashad as Cliff's attorney wife, Clair. Three of the five Huxtable children are still being seen on a regular basis: Tempestt Bledsoe as Vanessa, Keshia Knight Pulliam as Rudy, and Malcolm-Jamal Warner as Theo. Also back after a year's hiatus as star of the spin-off series A Different World is Lisa Bonet as daughter Denise, though the actress' pregnancy would severely curtail her appearances this season. Likewise, oldest daughter Sondra (Sabrina Le Beauf), now the wife of Elvin Tibideaux (Geoffrey Owens) and the mother of twins Nelson and Winnie (born in an hour-long episode, originally aired November 10, 1988), is only seen on a sporadic basis. Season five is distinguished by the fact that Theo has graduated from college and is attending New York University for graduate school, while Denise has dropped out of Hillman College and is preparing to journey to Africa as a photographer's assistant (a plot development which neatly coincides with Lisa Bonet's maternity leave). Likewise worth more than a passing nod is the episode "If the Dress Fits, Wear It," which features appearances by series regular Phylicia Rashad's sister Debbie Allen and husband Ahmad Rashad. And in the episode "No Way, Baby," Sammy Davis Jr. makes one of his last TV appearances as a cranky old cuss named Ray Palomino (Davis earned an Emmy nomination for his performance). ~ Hal Erickson, Rovi
