The Butterfly Mouse (La parpaja topola) is a dramatic monologue by Dario Fo.
A simple young goatherd was scared of women.
In his valley lived a priest who was having a relationship with a young girl.
The girl's mother came to see the priest and told him to desist - so the priest plotted to get the goatherd married to the girl, so that he might continue having his illicit relationship.
