I wonder if the guy sits down to pee these days--won't have been much left of his wang after an hour or so at -30 C. With the amount of vodka the guy had in him, he probably didn't feel the cold--at least for a while. One way of fixing frostbite (so I've heard, never needed to try it) is to stick ya dong in a glass of alcohol. That's how David Niven saved his inch when he got it chilled during ski-ing in Switzerland or somewhere. Imagine putting something like that in your autobiography. Seriously though, there were at least hundreds and probably thousands of German soldiers who died on the Russian Front in WW2 because they were stupid enough to do their business outside.
