Colder then a.....

So I was outside freezing and talking to this guy at work who had no coat on. I asked if he was crazy and he said no, he had been stationed in Chicago and Maine for 3 years so this wasn't that cold to him. He then mentioned the coldest weather he had ever experienced was -26 with a wind chill factor of -72. OH MY GOD! I can't even imagine that cold. Can anyone top that?
