I cast doubt on the Frenchness of the metal horns.

America does have that. It's the hang loose gesture with the thumb in front of your mouth.

Woah, Italy was seriously shortchanged here. Aren't the land of communicating pretty much everything with hands?

I like that the US "OK" symbol means "asshole" in Brazil.

Also that the only one for France is the devil horns, but done backward. They left out a lot of good French stuff, on top of all the Sicilian ones they skipped.

oh please, the dutch totally have some... typically bouncing the palm off the top of the forehead and arcing the arm forward and up. With one hand while riding a bike and almost killing you.
