I spent a summer in germany a couple of years ago and there were some crazy dutch people there who collected different words from different languages. The word they chose to represent sweden was ofcourse "knäckebröd". It sounded funny when they said it. They pronounced it on the last syllable, like knaeckebRRRRrroe.
The were drunk. And that made it sound even funnier. I was just eleven or twelve. So at the same time it was a bit scary.
:-D
