Hah, yeah. I have never had that problem. Never was somewhere with an outhouse when it was that cold. Though I did live somewhere that it got to -40F for a while every year. Once you know how to dress for it and to stay out of the wind it's not that bad of a problem.
On the other side. That sounds like it builds strong character ;) Its basically just a stoic mindset. Take cold showers and get used to them because one day you may not have a choice.
Some of the crew who weren't as used to the cold had to build up their courage before they went out.
I had a ritual initiation for newbies up to camp. Their first trip out to the outhouse I would quietly sneak out there after they shut the door, throw a lit pack of firecrackers under the outhouse. Usually the rest of the crew were standing on the porch awaiting the anticipated entertainment. Lol! Good times.
The seat wasn't all that bad, skin touching the seat got cold so fast that the pain went away within about 20 seconds, replaced by numbness.
Hah, yeah. I had friends that would do shit like that. I would definitely be startled after the first pop but then after that I would just be waiting for it to end and finish up. Head out "ok, who thinks they are funny".
Good natured fun and camaraderie.
