Family Matters

A spinoff of Perfect Strangers, Family Matters began as the at-home adventures of elevator operator Harriette Winslow and her multigenerational family. But midway through the first season, Jaleel White made a one-shot appearance as neighborhood nerd Urkel. With oversized glasses, undersized body, screechy voice and indomitable self-confidence, Urkel proved irresistibly funny, turning White into an overnight sensation and a new star of the show.
