Family Matters - Season 2 Episode 9 -

To get Urkel off her back, Laura directs him to a shy, withdrawn classmate named Susie. Urkel's magic touch gets Susie out of her shell, but he decides that, although Susie is very nice, Laura is the one he really wants. Meanwhile, Carl fails to notice the obvious about a seductive new neighbor named Loretta... that is, until she gives him a pair of musical underwear and suggests he demonstrate them.
