Technically they're not "fairy tales" because there are no fairies in them. The Germans call them "Marchen" and sometimes here they're called "folk tales," because that's what they are.
But whatever you call them, they are a repository of age-old wisdom. Their purpose is to entertain and educate, and that's exactly what they do.
The first is a Grimm's folk tale called "King Roughbeard" (or "King Thrushbeard") and to read it click HERE. I need say no more about it because it's self-explanatory.
The second is another Grimm's, and it, too, is self-explanatory. It's called "The Fisherman and His Wife," and to read it click HERE.
(By the way, "The Husband Store" can be considered a modern-day retelling of King Roughbeard. And in some ways, "The Fisherman and His Wife," too. To read it, click HERE.)
