Well, apparently there's this in-comic joke going around about Finland being a hard-drinking depressive knife-wielding homicidal maniac because his
national dish looks like something plopped on a plate*.
And also
because Åland wanted to leave him to join Sweden†.
* I have never seen actual pictures of
mämmi, so I have no idea if there really is any resemblance or not. Perhaps one of our Finnish members can weigh in on the matter.
† I should warn for large-font swearing on that comic, in case anyone is looking over your shoulder at work.
