So I have a story related to this. I teach English in Korea. One time, two 11-year-old students chose kopi luwak as a topic for their in-class (no research) project. I asked what that is, as I had never heard of it. They explained in pre-intermediate English that there is a cat that poops coffee beans. I didn’t believe them at first, because it sounded so silly. But they urged me to look it up. At first, I got confused between ‘kopi’ and ‘coffee’, because Korean has no ‘f’ sound and substitutes a ‘p’ sound. But when I finally found the Wiki page, I was blown away. The fact that this is real would be so funny if it weren’t for all the abuse another user pointed out.
