Answer
Family Matters is the sitcom on which Jaleel White played the iconic character Steve Urkel. The show, which aired from 1989 to 1998, followed the Winslow family and their misadventures with their next-door neighbor, the lovable and often-annoying Urkel. White's portrayal of Urkel, with his signature suspenders, high-pitched voice, and catchphrases like "Did I do that?" and "Whoa, Mama!", made the character a pop culture phenomenon.
