Is Finno-Ugric a magnet for this kind of speculation? I've talked with Koreans who are adamant about the existence of a relationship between Korean and Finnish.
The remaining connections of Korean still fascinated me when I first heard about it: https://en.wikipedia.org/wiki/Altaic_languages
> Various versions included the Turkic, Mongolic, Tungusic and sometimes the Korean and Japonic languages.
I was surprised of a kind of "UEH-ll" sound that you can hear in both modern turkish (their goodbye) and Korean language (don't have an example) and wondered if they had some kind of connection. Apparently they do!
Note that Uralic-Altaic and the like have been the fruit of an Anatolian Turkish nationalism and tend to speculate for nobilising the language.
Oh my yes.
