Wishing on a Monkey's Paw. It's an old fable, that a severed monkey's paw can grant wishes, however, the wish will not turn out the way you want. As an example, you could wish to be incredibly rich, but then all that money you got was stolen from someone else and you're arrested and thrown into jail. Or you could wish to live forever, but then you end up trapped beneath the ocean and spend eternity drowning over and over in terrible agony.
