<P> Wilson W. Wilson, (Earl Hindman)--Tim's neighbor and confidant . As a child, his parents did not allow him to speak to his neighbors, so he really likes talking to Tim and Jill . Wilson serves as an all-wise sage in the show, doling out advice to the Taylor family and seemingly always knowing just what to say to solve a problem . While most of his appearances were to help the Taylors, on seldom occasion someone who was in the extended family, or a nonmember, such as Al, would seek out Wilson's advice . He has traveled the globe and learned much from virtually every culture in existence . He has a Ph. D. in Cultural Studies, studying "extinct languages and forgotten cultures ." His house is full of artifacts along with a pet myna bird named Mozart who appeared infrequently . Wilson was married at one point, but his wife Catherine died long before the series begins (in a November 1994 episode, Wilson revealed that that month would have marked his and Catherine's 25th anniversary). </P> <P> At first it was unclear whether "Wilson" was his first name or last, but his full name is revealed as Wilson Wilson, Jr . In Season 6, it is revealed that his cousins are the Wilsons of The Beach Boys . He has a grown niece named Willow Wilson (China Kantner), who appeared regularly in the seventh season when she moved in with him for a while . His usual greetings are "Well, hi - dee - ho ..." or "Hi ho, there neighbor" or "good neighbor" when greeting Tim, "neighborette" when greeting Jill, and "Taylor lad (s)" when greeting the Taylor boys . </P> <P> 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 . </P> <P> Lisa (Pamela Anderson)--Binford's first "Tool Girl ." A secondary cast member on Tool Time, Lisa's job was to introduce Tim and Al and to hand them any tool they requested . When Pamela Anderson chose to leave Home Improvement to pursue a role on the syndicated series Baywatch, she was written out of the series after Season 2 and it was stated that Lisa was training to be a paramedic . She returned for a guest appearance four years later, having become fully qualified . </P>
