8 sotto un tetto

Steve Urkel was only supposed to appear once, but the audience's response was so overwhelmingly positive that the producers decided to make him a regular character. He became the most popular character of the show, so much that merchandise based on him was made, which included a talking doll, trading cards, posters, books, lunch boxes, T-shirts, and a limited-edition cereal called "Urkel-O's".

Guests always walked out of the Winslow's front door and then to the left, but in the picture that is shown as the Winslows' home, there is no walkway to the left. There are a few stairs outside that lead up to the front door, but walking to the left after exiting through the front door would only lead into a wall.
