A beautiful princess comes upon a frog in a meadow near her castle.
The frog hops into the princess' lap and says, "My lady, one kiss from you, and I will turn back into the dapper, young prince that I once was, and then, my sweet, we can marry and set-up housekeeping in yon castle with my mother, where you can prepare my meals, clean my clothes, bear my children and forever be happy doing so."
That night, as the princess dines on lightly sauteed frog legs, she chuckles to herself, "I don't f**kin' think so."
