Someone I know and like very much is a massive language geek, so I used the SATW characters to show the languages he can speak or is learning. My only fear is that I missed a few. If the geek in question sees this, he knows who he is.
Also, the Netherlands says "Nou, het is maandag, maar ik heb al de hele dag het gevoel dat het dinsdag is" which means "Well, it's Monday, but I've been feeling like it's Tuesday all day long".
Icelandic place names may sound exotic, but they're usually not very creative. Example: The most powerful waterfall in Europe, Dettifoss, just means "falling falls"
