I seem to remember hearing some crazy story about a factory that had a problem.
It was so cold outside, they had to get some special heaters installed onto the roof because parts of their cooling systems was getting too cold and freezing up.
The cooling system that was having problems was in place to help cool this factory's computer systems - including the computer that controlled the temperature - which was the major problem - the factory kept losing heat.
So, it was so cold outside, they needed heaters to warm up their cooling system that cooled the computers that controlled the heat in the building.
And what did this factory make?
Air Conditioners.
Now, this whole story could be completely made up. Perhaps I've got a few details wrong... I tried to search and couldn't find anything...
