Impact: The rise of quicksilver prices led to a secret society of alchemists forming in basements across the nation, all trying to recreate the philosopher's stone to avoid paying outrageous prices. Spoiler: they failed miserably.. Fact: Quicksilver is just a fancy name for mercury, which is great for making hats... if you want to go insane. Enjoy your headwear!.
  • Headline: General Marshall Denies Troops in South America. Impact: By denying troop deployment, General Marshall inadvertently inspired generations of conspiracy theorists who now believe the government is just a giant game of hide-and-seek. Spoiler: they’re still hiding.. Fact: This denial likely led to more people believing in UFOs, because if the government isn’t protecting us from aliens, what are they doing?.

Impact: The casual chat between mayors sparked a nationwide trend of mayors casually discussing their favorite ice cream flavors instead of pressing issues.
