Ha, see that makes at least a little sense.

I get ads in what I believe is Indonesian. And Vietnamese. But I think I did once, several years ago, watch a 5 minute video about Vietnamese pronunciations.

I've also gotten Welsh - but that's OK since I speak a bit of Welsh - and French, Italian, Spanish, Chinese, Japanese, Yiddish/Hebrew, Turkish, and what I think was Dutch, or maybe Swedish... something Northern Europe-y! Lol.

I don't know exactly what it is that YouTube thinks I'm doing tbh! Like, I have a handful of phrases in a lot of languages, but YouTube's estimation of my skills is waaaay high of the mark! Lol.
