Tool Time was the fictitious handyman show-within-a-show in the television situation comedy, Home Improvement. It was hosted by Tim "The Tool Man" Taylor (played by Tim Allen) and Al Borland (played by Richard Karn). The sponsor of Tool Time was Binford Tools, a fictitious tool manufacturing company. <Part of the show's attraction was its token "Tool Time girl", whose primary roles were to look good, be curvaceous, roll out various props and help introduce the two hosts. In the first two seasons, Pamela Anderson played Tool Time girl Lisa. When Pamela left the show, Debbe Dunning stepped in as her replacement, Heidi, who stayed until the show's cancellation. A fictional flashback to the first episode shows Mrs. Binford (most likely the mother of Mr. Binford, due to her age) playing the part of the Tool Time girl. Also in an ironic, but humorous twist, that "first episode" featured Tim with a beard, while Al sported a clean-shaven face, a direct opposite of their normal look. The 100th episode of Home Improvement (which aired in 1994) celebrated Tool Times 5th anniversary, thus revealing that Tool Time debuted in 1989
