Here is one from my country, Finland. People seem to generally think that the molotov cocktail was a Russian invention. It was actually developed in Finland, against Russian tanks during WW2. We didn't really have any anti tank equipment, so we had to use logs and snow to stop the tanks, then scorch them with molotovs.
You shall be pleasantly surprised that I am not Finnish, nor Russian, and knew that little fact, and have been persuading people that the Molotov was named as such by the Finns to make fun of the Russian Minister of Defence at the time.
On topic, it might surprise Americans to learn that the British do not have teeth made of wood or consisting of every shade of the colour yellow.
The British also invented television (And yes, Scotland is part of Britain so don't go "No it was the Scottish"), and the all-powerful refridgerator, and the worldwide web was created by a British man working at CERN (and no, not the internet. America invented the internet. The worldwide web is different, and it's a British invention).
