Phylicia Rashad became pregnant during The Cosby Show's third season, but you'd never know it from watching an episode. That's because America's favorite TV mom hid it literally. Clair Huxtable hid behind tables, kitchen counters, piles of jackets basically, anything that would disguise her ever growing "situation." The show's producers even scooped out the mattress of the set's bed so that Clair's stomach wouldn't show when she and Cliff lay down for a nighttime scene. Condola Rashad was born in December 1986 with plenty of time for her mom to slim down before Season 4 (the one in which Theo goes to the prom).
