Steve Urkel

Steven Quincy Urkel is a fictional character on the American ABC/CBS sitcom Family Matters, portrayed by Jaleel White. Originally slated for a single appearance, he broke out to be the show's most popular character, gradually becoming its protagonist. Due to the character's off-putting characteristics, a tendency to stir up events, and his role in the show's plotlines, he is considered a nuisance by the original protagonist's family, the Winslows. However, they come to accept him over time.
