When I was in school, world maps were generally contiguous rather than splitting Asia to center North America. We had separate maps to show the continents & countries in more detail, but generally the world map was centered on the prime meridian.
As for the last map, aren't the "Americans R Stoopid" jokes getting old? Everyone already knows, for the most part Americans aren't the most intelligent, well-informed citizens of the world. (That distinction belongs to South Koreans and the Japanese, respectively.) It's getting rather redundant at this point, don't you think?
