I have been told this! But dealing with "the potato in your mouth" language is already hard enough.. it'll take me some time to get the Swedish down pat. First, however, Danish and Icelandic. XD
Our Danish teacher had gone on and on about the sing-song sound of Norwegian vs the "Potato Danish". I LOVE Danish, and I don't think it's as awful as he made it seem. although, so many spud jokes do run rampant in classes. XD
