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?

Probably someone did. Not all English-speakers know about the first two, or have thought to ask.
Yup this was me. I knew it was the third, but it never occurred to me to ask what the other 2 were
TBH I knew about the Kaiserreich, but I had to look up the first one myself. It was the Holy Roman Empire. (Which wasn’t really much of a reich, but the Nazis weren’t noted for their attention to historical accuracy)
I daresay that 99% of “English-speakers” never wasted a thought on why the Third Reich actually was the third.
And honestly, it could be that 90% wouldn’t know what the HRE was or who the Kaiser was once you told them. It’s just not a thing that usually comes up in everyday life.
