Someone was looking in the newest Google Earth at Greenland for examples of Global Warming. What they noticed as an almost 100 kilometer orange rectangle in the middle of the island. Some people state that it is the roof of Santa's workshop. I just think it is where Slartibartfast and the Magratheans screwed up.

If you think about it, Wikipedia is sort of like The Hitchhiker's Guide to the Galaxy.
