And then Bunny did what he should not have done. He pulled some boxes and rolled a barrel over to the middle of the barn floor until he had a sort of platform under the trapeze Mart had put up to practice on. Then Bunny climbed up, got hold of the swinging bar and swung his legs over. Then something queer happened, for the first thing Bunny Brown knew, there he was, hanging upside down with his legs over the trapeze and his head pointing to the pile of hay in the middle of the barn floor.
