A happy man has a giant dump truck and he spends the day giving a fun ride to a bunch of farm animals. As the dumper rises and lowers, the animals are given the ride of their lives. There's not much story here, but the book is a lot of infectious fun. Tibor Gergely's illustrations are always a delight and even his realistic machines always seem to have personality. This is a true classic that's really all about playing and having fun.
