Joanna Kerns made it OK to lust after Mom. As taboo as that urge may be, her portrayal of the hard-wanking matriarch of the Seaver clam on the hit TV series Growing Pains gave Mr. Skin growing pains in his pants. She started her career back in the late '70s in such films as Ape (1976) and Coma (1978). Sadly, since hitting the big time she has pretty much, aside from a bit part in a film here and there, spent the better part of her career on the small screen and thus hasn't revealed a whole lot in the way of skinage. She did manage to get naked in The Watchman (1992), though all we were treated to was a brief shot of her hellacious heinie and a load of body-double nudity. But mama's got back, and it's all the flesh we have to fantasize with for stingy Joanna.
