A Peasant Was Arguing With His Wife...

... when, in a fit of rage, he threw her down the well.

A week later, he goes back to the well, hoping she got calmed, and he thew down a ladder in the well.

The only thing, it's the devil who got out, and thanked the peasant.

-- Gosh, thanks! It was getting unbearable with her down there! Well, to thank you, take this little bunch of herbs. In a few months, when you'll hear that a princess is possessed by the demon, go see the king, and burn the herbs near her, and the King will reward you. But I warn you that this trick will only work once!

Sure enough, in a few months, he learns that the princess is possessed by the demons, and no exorcism is able to stop it. So he goes to the capital, and asks to see the princess.

Since nothing they tried has worked, they let him in, and he burns the herbs the devil gave him, and sure enough, within minutes, the devil leaves the princess, probably blinking at the peasant, before vanishing.

Everyone is relieved that the princess is saved, the King foremost. So he rewards the peasant with the governorship of his province, and he gets very wealthy and successful.

A few years later, another princess is possessed by the demon. When asked to repeat his feat, he said that he is no longer able to do it. The King, furious, has him summoned to the princess.

When he gets there, the devil recognize him and says "hey! I told you that the trick only works once!"

-- Oh, I'm not there for that; I just wanted to warn you that my wife just got out of the well and that she is pissed-off at you, and she is looking for you right now.

The devil let a blood curdling scream, and fled away so far that they never heard of him ever again...
