I left my campsite and hiked south for 3 kilometres. Then I turned east and hiked for 3 kilometres. I then turned north and hiked for 3 kilometres, at which time I saw a bear inside my tent eating my food! What colour was the bear?
ANSWER: White. The north pole is the only place where you can travel south, then east, then north and end up at your starting location. Since the only bears that live at the north pole are polar bears, it must be white!!
