8. MAYIM BIALIK

The former Blossom star never had conventional roles, which might explain her equally unconventional public persona. She seems to have plenty in common with her genius character Amy on The Big Bang Theory, including her personal style and the fact that she’s a real life scientist. Though she may not be as socially inept as Amy, everything about Bialik exudes an inescapable sense of nerdy nostalgia that makes it difficult for us to escape those memories of the early '90s.
