As we've discussed before, the Brothers Grimm were a pair of child-hating lunatics. Here are a few more of their baffling tales, because you should never be short of ways to frighten and confuse children.
5"The Girl Without Hands"
A man accidentally trades his daughter to the devil for wealth, because that's apparently something you can do by mistake (maybe he checked the wrong box on the application). But the daughter fights back by washing her hands, enraging the devil, who prefers everything to be covered in fart dust.
Predictably, the devil just has her hands chopped off. However, she cries so much that her blood-spouting stumps are washed clean, and the devil throws up his hooves and calls the whole deal off.
The devil can't make use of a crying woman with hook-hands?
