After six years of Urkel-agony, the Winslows finally admit themselves into therapy where we look into the history of the chaotic effects that Steve has had on the Winslows. In the end, Steve begins to realize the damage he has done but Harriet defends his case by explaining the good things Urkel has done for the Winslows that overpowers the bad (including the two times that Steve has saved Carl's life). On the way out, Urkel causes more damage to the therapist's office than he did coming in. (thetvdb.com)
