I guess I should post this here. Today I saw again an a bit older ad for a national alternative radio station called FM4. The ad uses the image of the Struwwelpeter. For anybody who doesn't know, the Struwwelpeter is a german childrens story (free english eBook version) from a collection of such stories that go by that same name. The story is about a boy named Peter who refuses to groom himself, growing messy hair and elongated fingernails.
