as is often the case with these types of videos, it's impressive until they get to swedish and the illusion is shattered
have to assume they're pretty much just guessing with a lot of the others too then and i mean... who can't just read a bunch of words from another language if it doesn't matter how it sounds
It's ok, he's referring to Stockholmska which we make fun of up here too. Danish is objectively the ugliest Scandinavian language though (sounds like they're constantly trying not to vomit), but it's one of those things that are too real and insensitive to make fun of.
Anyway, it wasn't completely off and being German(?) they are among the few who would get the "ä" in "känns" right (unlike f.e. American), but the hard "k" like in "mortal kombat" betrays their unfamiliarity with the word (should be "sh" like in shoes").
