Joyce

Guy finds his eldest and thickest sister Joyce residing in a nunnery, living a perpetual childhood to the chagrin of the Mother Superior. Joyce insists that the Virgin Mary came to her as a tree when she was a child and dropped a conker on her to tell her to become a nun, and she appears never to have fully recovered from the blow to the head. Guy must convince her to leave the sisterhood and return to her biological sisters, but he soon learns that nothing short of a miracle will persuade her to abandon her pious pursuits.
