10. Steve Urkel
The dictionary should have a picture of Urkel’s face next to the word “nerd.” Aside from the moments when he’s in Stefan Urquelle mode, Steve Urkel was the poster child for geeks everywhere. Argyle sweater vests, highwater denim, and bifocals with the string attached were all his staple pieces. We got to give the dude credit since he eventually got Laura Winslow to give in by the end of Family Matters, even though it did take nine seasons.
