The man-woman and the frog

A woman tells a story about a man who likes to dress as a woman. The chief in the story is attracted to this man, and not knowing that he is actually a woman, pays his/her dowry. When the hare tells him that his bride to be is actually a man, the chief organizes a festival where everyone takes their clothes off. In the meantime, a female frog agrees to exchange her sex with that of the cross-dressing man. On the festival, the man appears to have a vagina. The frog, however, turns out to have been pregnant, and dies since she cannot give birth.
