Mary-Kate and Ashley Olsen
Born June 13th, 1986, in Sherman Oaks, CA, Mary-Kate Olsen is one-half of the multimillion-dollar franchise known as The Olsen Twins. Long before the pair had unwittingly indoctrinated themselves into the hearts and minds of adoring pre-pubescent girls (and vaguel creepy fraternity boys), however, Mary-Kate and her sister, Ashley Olsen, were simply the youngest members of the long-running sitcom Full House, which hired them just a year after their birth. Because of U.S. child-labor laws, the girls took turns playing Full House's resident cute baby girl, Michelle Tanner. Before long, Mary-Kate and Ashley had their own catchphrase ("You got it, dude"), which reverberated in the ears of Uncle Jesse (John Stamos) and throughout American audiences loudly enough to merit a TVQ rating -- the sitcom world's most prominent popularity contest -- second only to Bill Cosby.
