One of the enduring folktales among the Mount Kenya people is the one about a boy who paid a visit to his uncle many years ago. His uncle received him well but his wife, who was fuming for no reason, served him ugali and houseflies stew.
Later, the uncle realised that this might get him in trouble with his in-laws. So he slaughtered a cock for the boy to erase houseflies stew from his head. Then he asked the boy what he was served at his place, only for the boy to answer that he was served housefly stew.
