 The episode that ensured "Family Matters " success. It all began with Laura bemoaning her inability to get a date with cute classmate Mark for the school dance. Eddie and Carl make well-meaning attempts to set Laura up with someone. It is Carl who - in a decision he d live to regret - sets his daughter up with Steven Q. Urkel. The quintessential nerd drives everyone batty just being himself. Even though Laura eventually gets over her shyness and asks Mark out, Urkel decides to stay until 10 p.m. - the earliest his folks want him home - and makes himself at home!
