Have a look at a standard Chinese/Hong Kong/UK power point - 

The earth pin is at the top and plugpacks (I like to call them "wall 
warts") are plugged into them in a way we'd consider upside-down.

Bring in economies of scale in mass manufacturing and it becomes cheaper 
to just replace the pins at the head of the plugpack for different 
international markets rather than redesign the whole thing.
