Anna is bored and must be amused,

Everyone must post the weirdest fact they can think of. Stuff that sounds like it goes against common sense and what we all think we know.

Here's mine to start you off:

There's no such thing as Fish.

How so, you poor little chumpettes say? Well, Fish as a group of animals just doesn't make any sense, the animal that would be classed as Fish are so varied that mostly you can actually group many of them better with animals that are non-fish. For example, a salmon has more in common with a dolphin than it does a hagfish, so why isn't a dolphin a fish?

Fact is fish as a term makes no sense. There's no such thing as a Fish.

Ok, now your turn, amuse me with your counter-intuitive knowledge.
