When I learned Norwegian, my teacher used to joke that all of Scandinavia spoke Norwegian. It's just that the Swedes were pronouncing things wrong and the Danish couldn't spell it correctly.
"Society invents a spurious convoluted logic tae absorb and change people whae's behaviour is outside its mainstream. Suppose that ah ken aw the pros and cons, know that ah'm gaunnae huv a short life, am ah sound mind, ectetera, ectetera, but still want tae use smack? They won't let ye dae it. They won't let ye dae it, because it's seen as a sign ay thir ain failure. The fact that ye jist simply choose tae reject whut they huv tae offer. Choose us. Choose life. Choose mortgage payments; choose washing machines; choose cars; choose sitting oan a couch watching mind-numbing and spirit-crushing game shows, stuffing fuckin junk food intae yir mooth. Choose rotting away, pishing and shiteing yersel in a home, a total fuckin embarrassment tae the selfish, fucked-up brats ye've produced. Choose life. Well, ah choose no tae choose life. If the cunts cannae handle that, it's thair fuckin problem. As Harry Launder sais, ah jist intend tae keep right on to the end of the road..."
> The term Scandinavia always includes the mainlands of the three kingdoms of Denmark, Norway, and Sweden. Norwegian dependencies, including Svalbard and Jan Mayen, are usually not seen as a part of Scandinavia, nor is Danish Greenland. However, the Danish Faroe Islands are sometimes included, as sometimes are Iceland and Finland
Finnish isn't even remotely related to the Scandinavian languages. If you're going to be needlessly pedantic and contrarian, at least put a little more effort in it than glancing at Google Images.
Finland is associated with Scandinavia by virtue of being dominated by actual Scandinavian countries (notably, Sweden) for so long, which influenced the culture. But it's not Scandinavian per se, any more so than, say, Georgia is Eastern Slavic. Ditto the language - influenced, yes; belonging to the same group, not at all.
