There are a number of great uses for home cooling systems. Generally, people just use them to try to beat the heat during the summer months. However, in October last year, a crazed man in Hong Kong tried to turn his AC unit into a weapon when he attacked famous director Michael Bay on the set of Transformers 4. The report on TMZ sums the situation up well. It reads, “Bay almost got clobbered by what appears to be a drugged out crazy who swung an air conditioner at his head on the set.” Fortunately, Bay was able to wrestle the unit away and security restrained the assailant before anyone was hurt.
