De Grandpre-de Pique (1808)
Monsieurs de Grandpre and de Pique discovered that their mistresses were actually singular, a Mademoiselle Tirevit cheating with both of them. Rather than kicking her to le curb they decided that honor – and sanity – both needed to be shot at. FROM THE SKY. They ascended to 2,000 feet in hot air balloons and started blasting at each other. De Pique managed to miss an entire hot air balloon with a blunderbuss and therefore deserved everything which came afterwards (de Granpire’s buckshot through his balloon and the ground through his everything.)
