This is a funny mock tale laced with cynicism:

Once upon a time,in a land far away,a beautiful princess happened upon a frog as she sat contemplating ecological issues on the shores of an unpolluted pond in a verdant meadow near her castle. The frog hopped into the princess's lap and said, "Elegant lady, I was once a handsome prince, untill an evil witch cast a spell on me. One kiss from you, however, and I will turn back into the dapper, handsome, and charming young prince that I was, and then, my sweet, we can marry and set up housekeeping in your castle with my mother, where you can prepare my meals, clean my clothes, bear my children, and forever feel grateful and happy doing so."
That night, on a repast of lightly saut`eed frog legs seasoned in a white wine and onion cream sause, she chuckled to herself and thought, " I dont think so."
