How will Wilson hide his face this week? That's what "Home Improvement" viewers have been wondering for the past eight years. It was a challenging question the show's directors also faced. After Tim Allen came up with the idea of having a neighbor shown only from the nose up, the directors had to think of clever new ways to hide Wilson (Earl Hindman) whenever he was in a scene. During the show's 201 episodes, Wilson has been hidden by some pretty funny things.
