 FAKE: An African elephant, identifiable by its long ears, passes  through town and Joe collects its dung. Later, flowers grow on the  dung and he presents them to Lily, who says that the flowers only  grow on the dung of elephants native to southeast Asia. Lily claims  to have written her senior thesis on this species of flower, so it  is unlikely that she has misidentified them or that she is mistaken  about where they grow.
