There are things you just have to know. How to make a tax return, how long to cook pasta or where you put your key in the morning. And then there is knowledge that serves absolutely no purpose – except suddenly to show off at the next conversation. This is exactly what we are doing today!

For example, did you know that Octopuses have three hearts? Two of them supply the gills with blood, while the third supplies the rest of the body. Even more curious: When swimming, the body heart temporarily stops beating. Perhaps this is why octopuses prefer cozy crawling on the seabed.

Bananas also have more to offer than you look at them. Botanically, bananas are berries, but strawberries are not. So the next time you order a strawberry cup, you can at least unnecessarily point out that its name is botanically somewhat misleading.

And who thought that snails with their leisurely lifestyle already had enough peculiarities: Many snails have a so-called Radula, a rasp tongue with numerous tiny teeth, with which they work their food. Depending on the species, there may be thousands of such teeth.

Why should we remember all this? Actually not at all. But that's what makes useless facts so entertaining. They surprise, start conversations and occasionally raise the important question:

“Why the hell do you know?”

And there is only one suitable answer to this:
Because useless knowledge is sometimes the best knowledge.
