Hoist by His Own Petard/Fairy Tales

• In many Fairy Tales, someone describes the crimes to the villain without using any names and asks what a suitable punishment would be; the villain, who has usually framed the hero or heroine for the crimes in question, then (often gleefully) prescribes a horrible punishment and is subjected to it. These include:
  • The Goose Girl
  • The Three Citrons
  • The Twelve Wild Ducks
  • The Stag and his antlers
• In the fairy tale Hansel and Gretel, the witch instructs Gretel to stick her head in the oven to see if it is hot enough (with the intention of pushing her in to be cooked). Gretel feigns ignorance, causing the exasperated witch to stick her own head in the oven to show Gretel how it is done... and she is inevitably subjected to the same fate she had planned for the two siblings.
