If a bird poops on your house, on your car, or – heaven forbid – even on you in Russia, that means you’ll soon be coming into some riches. And, though it may seem counter-intuitive, the more bird poop you experience, the more money you’ll be getting.
It’s unclear where exactly the idea came from. It’s entirely possible that the people who were getting pooped on, or those who witnessed it in pity, chose to have the most optimistic reaction to their fecal fate.
While the origins of this longstanding myth are unclear, there have been people in history who have gotten rich off poop. Gold miners in the United States in the mid 1800s found that they could sell bird poop for fertilizer and get, well, stinking rich off the stuff. So maybe the belief is a throwback to old farmer fertilization beliefs of the past.
