the only thing i really know about friesland is, its dialect is the closest to english.

There are a couple of Frisian languages spread out in the Netherlands, Denmark, and Germany. The same Wikipedia (cum grano salisch) has a sample text from West Frisian (Frysk). I knew a Frisian once, and showed him Beowulf in Old English. He was able to pick up the meaning of the text better than Anglophones. The Frisians are also the butt of many moron-style jokes in Germany. A famous German comic, Otto Waalkes, comes from Friesland, and he sometimes plays to the stereotypes that other Germans have about that area.

Ceci n'est pas un seing.
