If I may, I think I discovered something. It's about the power sockets.
Power sockets reflect peoples deepest feelings in the respective countries.
For instance, the americans are scared of everything, thats why they came to that country in the first place. Israelis are not quite sure about anything and also a little scared, Australians are... oh this one will be trickier... australians are sneaky and just pretending to be jovial, while their power sockets tell the truth, that they feel helpless, stuck in a country with oversized rabbits and birds and poisonous everythings. British sockets are the wrong way up, but they of course think its the right way up, just as left is the right side of the road. Our swedish and german plugs do not tell us anything, they are just two black holes representing a quiet and melancholic state of mind. In France, the power sockets look like something erotic, and in Italy they are all into threesomes.
Explanatory images below
American scared senseless socket (or alternatly, outraged at sex modded into GTA-games)
French erotic socket (two holes and a big shiny rod, hmm?)
The german schutzkontakt used sweden is melancholic and depressed, void of any emotional signal
British right way up connector (cause they dont give a damn if your un-british appliance doesnt fit, it wont even work because their electrical system is just as backwards, or correct if you ask them. But if you do ask, you're wrong anyway, and probably french.)
Israeli plug, not all that sure about anything, a little suspicious
Australian sockets, looks like the man from Scream, because inside all australians are screaming to get away from the poisonous animals and mutated rabbits with pouches and spiked tails
So, how about that for a study?
