Sorry Darren, someone mounted the light switch upside down.
[Who will get the reference?]
So ON is OFF and OFF is ON on the other side of the equator? 
Switch UP to turn it off in countries of the faded Empire, except Canada?
What else is upside down or is right side up? 
Traffic drives on left side of the road and driver sits on the right (which makes it very hard to drive American cars)****
Do you walk on your ceilings? 
We probably could if we wanted to!
**** Other problems driving American cars:
Hard to reach steering wheel from drivers seat.
Wipers start when approaching a turn.
