6Construction-equipment loving boys will adore this humourous twist on the classic nursery rhyme. Someone has done a lot of work building a house. Someone has been operating a cement mixer, driving a bulldozer, and using a forklift to build walls, frame windows, and nail down a roof. Someone has built a big, strong home for Jack. But is this the house that Jack built? One tired puppy dog disagrees in this story about getting what you work for.
