Early on, Tim Allen would deliberately misquote lines in some scenes to help child actors Zachery Ty Bryan, Jonathan Taylor Thomas, and Taran Noah Smith, so that they would feel less pressure about getting their own lines wrong.
Tim Allen stopped grunting as the seasons progressed due to the strain it eventually started to cause on his throat.
As promoted by Tim on "Tool Time," Binford Tools features in Toy Story (1995), which also starred Tim Allen. You can see the reference Woody tries to help Buzz escape from Andy's evil next-door neighbor's room. Woody pushes a red toolbox off the side of the counter, and when the toolbox comes into the shot, you can see the Binford logo on the toolbox.
Jonathan Taylor Thomas wanted to quit acting to focus on academics instead. He left the show in 1998, making occasional guest appearances after that. He did not appear in the series finale, except in archived footage.
After universities and colleges in Michigan sent Tim Allen sweaters and t-shirts to wear on the air, he did so and followed in the footsteps of Ted Knight in Too Close for Comfort (1980).
