- Headline: Paul A. Arnswalde Event Overview. Impact: Paul A. Arnswalde's name is mysteriously omitted from history books, leading to a global conspiracy theory that he was a time traveler himself. This causes a surge in amateur historians trying to uncover the 'lost' time travelers of the past, inadvertently creating the first ever 'Time Travel Convention' in 2025.. Fact: Did you know that people have been known to mispronounce 'Arnswalde' for decades? Some even think it's a type of exotic fruit!.
- Headline: Launch of 'Dark Passage' Starring Bogart & Bacall. Impact: 'Dark Passage' becomes an accidental blueprint for future crime dramas, leading to a world where every movie features a brooding hero and a mysterious girl. This culminates in a cinematic universe where Bogart and Bacall are worshipped like deities by future generations, resulting in a bizarre religion that promotes trench coats and sultry whispers.. Fact: Fun fact: Humphrey Bogart was once quoted saying, 'I’m not a star, but I play one on TV.' Too bad they didn’t have TV back then; he might have made it big!.
