I agree with the previous note. There's some cool appearances by Gösta Ekman and Björn Gustafson in this pic, they're the ones to lift it off the ground making it one of the Swedish comedy classics. For instance, seeing Gösta, "Sickan" or "Charles Ingvar" as the character likes to be called, attempting not to be seen by the security guard while facing that his hideout; a giant lamp hanging from the roof, slowly but safely slides downwards since it can't carry his weight - that scene is a real classic. This is a movie I'd recommend anyone to see. It's more fun than most american comedy movies I've seen, and I've seen many.
