The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

I have to admit that this is rather old. So old, in fact, that it does not refer to the Third Reich but the Kaiserreich.
I don’t think anyone thought it was about the third reich
Probably someone did. Not all English-speakers know about the first two, even though they’re implied by “third”.
That’s better but not that by much. A few years ago Germany raided some very rich and very well-armed wackos who wanted to bring back the Kaiserreich.
