Why were fabliaux copied into manuscripts owned by religious houses?

In the context of Anglo-Norman literature, a small number of fabliaux have been discovered copied into manuscripts held by religious houses. It is believed that these comic, often coarse, and cynical verse tales were preserved in these monastic collections primarily for exemplary purposes.1

While fabliaux were generally characterized by their realistic observation, erotic themes, and mockery of social classes, their inclusion in religious manuscripts suggests they may have been utilized to provide moral instruction or to serve as cautionary examples of human vice and folly, rather than being intended solely for entertainment.213
