Random facts might seem like they aren't worth much on the surface, but you never know when they'll come in handy. I mean, that's basically the entire plot of "Slumdog Millionaire!"
While being a trivia buff doesn't necessarily guarantee you'll win a million dollars, I can say it's definitely helped me out in various random ways - from having interesting conversation starters at parties to being able to relate to someone who might be an expert in a particular field I just so happened to be vaguely familiar with. On one occasion, it actually *did* help me win a random bar trivia contest I entered with some friends on a whim!
If you happen to be a trivia lover like myself, you'll definitely love these random bits of trivia
