while growing up, i remember many times when the thermometer on the front porch stopped at -38... since that is the freezing point of mercury and we didn't have an alcohol thermometer.
once i got over the idea that i was going to be a full-time athlete, i learned the freezing point of beer, wine, and other spirits. which a few times meant a clean-up of the interior of a car with such things left in it over night.
One true story i know (not a personal acquaintance) is of that a guy out snowmobiling at -42 kept a bottle of schnapps in his snowmobile's tool box. Snowmobile suits make bombing around on them at that temperature recreational for cooped-up people. He stopped, took a huge gulp from the bottle, and instantly his throat froze solid and he asphyxiated before it thawed. It was an object lesson not lost on fellow north dakotans.
