Tool Time was conceived as a parody of the PBS home-improvement show This Old House. Tim and Al are caricatures of the two principal cast members of This Old House, host Bob Vila and master carpenter Norm Abram. Al has a beard and always wears plaid shirts when taping an episode, reflecting Norm Abram's appearance on This Old House. Bob Vila appeared as a guest star on several episodes of Home Improvement, while Tim Allen and Pamela Anderson both appeared on Bob Vila's show Home Again.
