who was the guy behind the fence in home improvement
List of Home Improvement characters A visual gag is that Wilson's face isn't shown in its entirety, originally (and most commonly) with the bottom half obscured by the tall privacy fence that separates the neighbors' yards. This gag is extended over the course of the series with other objects (or a beard) obscuring the bottom of his face, or the bottom half showing but the top obscured (such as by a mask), or his full face shown but covered by paint. The audience finally sees Earl Hindman's full face unobscured in the series finale's curtain call. This was based on how Tim Allen saw a next-door neighbor when he was growing up.
