Maps that offend the entire planet with a single image.
The United States As Seen By A European
We had to wait until adulthood before we were able to blanket the entire globe in xenophobic stereotypes. A lot of time would have been saved if these were the maps taught in our elementary schools instead of those annoying "geographically accurate" ones. Considering the state of the world right now, the days of printing maps according to country names and borders are long gone. There's no telling which country will be next to cease existence as a result of war, economic collapse, or the election of Rick Perry.
