My DM used to be a primary school teacher. I remember her doing a lesson on fairy tales, and how to write your own in your own way, but only getting the same old stereotypes as the class didn't see what she was getting at. So I wrote them one about how an evil dragon came to ravage a kingdom. So the king sent out messengers far and wide offering the hand of his daughter in marriage, and the crown after his death, to anyone who would rid the land of this peril. Naturally the princess was very unimpressed by this. So she went off, sorted out the problem with the dragon (by bravery and intelligence), came back and told her father that this meant not only could she marry whoever she wanted not who he said, but that she was more than capable of ruling after him.
Some of the girls' stories after hearing that one had changed quite gratifyingly...
