Tim Allen, Richard Karn on reuniting decades after 'Home Improvement': 'Doesn't feel like 30 years'

"Home Improvement" stars Tim Allen and Richard Karn reflected on what it was like working together again on History Channel's "Assembly Required."

Now, three decades after the comedy first premiered, the two are reteaming for a new show, "Assembly Required," where they tap into their DIY roots to host a reality competition series that sees contestants rebuild everyday household items. Although the final episode of "Home Improvement" aired nearly 22 years ago, Allen, 67, and Karn, 65, have remained close.
