More with English subs on YouTube just write 'Pasila english subtitles' in the search bar.
I absolutely love this show, it shows really some true elements of Finnish mentality and absurdity. And I love the voice actors, the one who plays the chief of police is voiced by one of the greatest comedy actors of Finland Kari Hietalahti.
I hope you guys like it too!
