Jonas Karlsson, who is Swedish, worked really hard not to speak as a Swedish-speaking Finn (Swedish is an official language in Finland, spoken as a first language by a significant minority of the population), but rather as someone who speaks Finnish as his native language and learned Swedish later in life. Karlsson also manages to mispronounce the "sh" sound as Finns do in Swedish, even when he speaks with a Stockholm accent.
