Tim (Tim Allen) starts the training early as he instructs youngest son Mark (Taran Smith) on the proper way to grunt.

Zachery Ty Bryan (Brad) learned early on how to make his voice heard on the busy "Home Improvement" set. Jill (Patricia Richardson) ministers to Tim (Tim Allen) after a little accident involving a table and some glue.
