Jaleel White

Then: Starred as the uber-dork Urkel on "Family Matters" (1989-1998), with hiked-up pants, enormous glasses and a voice that would shatter double-paned windows. At first Urkel was a neighborhood sidekick to the main family, the Winslows, but Urkel became such a ... moresensation that later seasons focused more and more on Urkel and his cartoonish, buffoonish presence. "I am a serious little nerd. I use verbs!"

Now: White grew up to be -- wait for it -- a very handsome man, and has worked steadily in TV and film over the past decade and a half, with roles in shows like "Boston Legal" and films like "Dreamgirls." He'll be seen later this year in a big-screen version of "Call of the Wild," with some other great where-are-they-now stars like Joyce DeWitt, Christopher Lloyd and Veronica Cartwright. Nerds really do rule.
