German fairy tales are pretty hardcore
This is from one of the stories in the illustrated book Der Struwwelpeter (The Shock-Headed Peter). The story is about little Konrad who keeps sucking his thumbs although his mother has forbidden to do it, ignoring the warning that the tailor will come and cut his thumbs off. This is what happened.
The book speaks for an autoritarian style of education and is heavily debated in Germany. I must admit that I was scared of some of the stories (especially this one) when I was little.
