Dr. Heathcliff ‘Cliff’ Huxtable

Dr. Heathcliff ‘Cliff’ Huxtable
The Cosby Show

Cliff Huxtable, played by (and loosely based on the real life of) Bill Cosby, stole our hearts in the '80s. As dad to five children -- Sondra, Denise, Theo, Vanessa and Rudy -- with wife Clair, Cliff was often humorous, but always endearing. Cliff had a penchant for making silly bets and played a monthly game of pinochle with his dad and some friends.
