Steve Urkel
Steve Urkel wears big red glasses.  He has a high-pitched voice and snorts when he laughs.  He wears his pants too high up on his waist.  He is in love with the oldest Winslow daughter, Laura.  Laura often tells him that she does not like him, but he does not listen.  Many of the episodes of Family Matters are about Urkel trying to convince Laura to be his girlfriend.
