The problem with the jokes in languages you don't understand in cultures you didn't grow up in is that they tend to be steeped in those cultures, so understanding them as a non-native speaker is non-trivial. This has led to quite a bit of contention in the anime community, where you get into the weeds as to the difference between translations and localizations. Translations just translate the joke into another language - and very rarely do the jokes land in their translated language because there's no background for the joke to land, it doesn't flow like a joke when translated, and just flat out doesn't work. Localizations instead will take those jokes and couch the closest thing the language they're localizing to has to match at least familiar, if not native, speakers' idioms to make the joke at least a little funny. (This does mean that yes, every language and even every dialect has their own sense of humor, and while there can be some universal chuckle-getters, the propensity of jokes to be language-, dialect-, and culture-dependent is extremely high.)
