The Girl with the Green Ribbon

 Mental Floss publishes a suitably off-the-wall post by Ellen Gutoskey, which takes its as its starting point the children's story "The Green Ribbon" by Alvin Schwartz published in 1984.

Alvin Schwartz's tale follows a well-travelled tradition in Gothic fiction, largely inspired by the imagery of the guillotine.  Early examples include Washington Irving's The Adventure of the German Student (1824) and Dumas's The Woman with the velvet Necklace (1849)

The (possibly mythical) Thermidorean bals à la victime expressed much the same anxieties: Ridley Scott's "Napoleon" has some atmospheric scenes:
