Tim is over the moon when he learns that his next episode of Tool Time will break Bob Vila's record for most consecutive tool show appearances - and to mark the occasion, Al and Heidi have arranged for a live on-location shoot where Tim can lay asphalt using a steamroller. But when Tim badly injures his shoulder the day before the shoot, his doctor informs him that he'll need emergency surgery and cannot film the show. Unwilling to be shown up by his nemesis Bob Vila, Tim sneaks out of the hospital to film his record breaking show - and gets so badly re-injured in the process that he has to miss the air show he was going to take Mark to that weekend. With Mark and Jill both furious at him, Tim has to figure out a way heal his son's opinion of him while healing his shoulder injury.
