Greatest carpenter since you know who comes to visit

Dave Lawrence, also known as Uncle Dave, came by. He brought his two assistants and they made quick work of replacing shingles on the side of the house. Off with the old, on with the new. Old shingles must have been damn near 40 years old. Dave travels in this righteous yellow bus of home improvement magic. No would be journalists, it's not a Herald truck, it's an emergency vehicle from an airport.

There's only one problem with Dave Lawrence. There's just one of him.
