  • Headline: Governess Accuses Attorney of Assault. Impact: This unfortunate event led to a boom in self-defense classes, which then spiraled into the rise of reality TV shows about 'Real Attorneys of Long Island'β€”the original courtroom drama.. Fact: In the 1920s, many people believed that lawyers were just like superheroesβ€”only instead of capes, they wore suits and carried briefcases full of paperwork..

Impact: The longshoreman's conviction led to a nationwide debate on the ethics of assisted suicide, eventually inspiring a hit TV drama series, 'Law & Order: Euthanasia Unit', which didn't exist but probably should have.. Fact: Assisted suicide has been a hot-button issue for centuries, but it’s still way less controversial than pineapple on pizza!.

  • Headline: List of Yesterday's Contributors to the Appeal for the Neediest Cases; CASE 112 Plight of a Good Samaritan. Impact: The plight of the Good Samaritan inspired a surge in charity appeals, which eventually resulted in the modern-day 'GoFundMe'β€”where people raise money for everything from medical bills to dream vacations..
