One might be tempted to draw comparisons, but it can also become an obsession. Still, that's exactly what Berliners tend to do, at least when it comes to their city.

Whenever it happens, Berlin suddenly isn't good enough for them, and they constantly feel compelled to draw comparisons -- not with just any old cities, but with the crème de la crème. "Berlin, the German metropolis, can once again measure up to the likes of London, Paris and New York," the city's then-mayor said shortly after the fall of the Berlin Wall.

The die-hard residents of the German capital don't like to aim any lower than that. They see Berlin as the sassy little sister of London, Paris and New York, a city that successfully contended for a spot in the exclusive family of cosmopolitan cities in the 1920s.
