The "Tool Time" audience is the actual live studio audience.
When the show went into syndication in 1995, the producers chose to film a new episode to kick-off the syndicated episodes, a first for a network series. Tim Allen and Patricia Richardson filmed part of the episode at the Marine Corps Air Ground Combat Center in Twentynine Palms, Calif., where their characters had a race, driving tanks on a mapped out course. Many Marines of 1st Tank Battalion were then invited to the studios in Los Angeles to watch the filming of the rest of the episode live from the studio audience.
While taping some episodes of Tool Time, Tim sometimes asks an unseen character, Klaus, to play music for Tool Time segments. Klaus Landsberg worked in the sound department on "Home Improvement".
Colleges and universities in Michigan sent star Tim Allen sweaters and T-shirts to wear on the air, and he did.
Binford Tools, the company that sponsors the Tool Time show, is named after a friend of the family of one of the producers.
