Once upon a time, a beautiful princess happened upon a frog in a pond.
The frog said to the princess, "I was once a handsome prince until an evil witch put a spell on me. One kiss from you and I will turn back into a prince and then we can marry, move into the castle with my mom where you can prepare my meals, clean my clothes, bear my children and forever feel lucky for doing so."
That night the princess had frog legs for dinner.
