Allen, now 67, and Karn, now 65, starred together in the hit comedy series for eight seasons from 1991-1999. They played Tim Taylor and Al Borland, respectively -- hosts of the fictional television series "Tool Time." ‘HOME IMPROVEMENT' STARS TIM ALLEN, RICHARD KARN ARE 'BACK IN THE SHOP' IN 'ASSEMBLY REQUIRED' TRAILER"When we started doing 'Home Improvement,' we had audiences watching 'Tool Time' that hadn't seen the show at all," Kern recalled.
