@mcc True story: my college roommate’s dad spent a year at a research station in Antarctica, where various random scientists from all over the world were stationed. They had a hot tub, and would amuse themselves by running straight out of the hot water into the sub-sub-zero temps really fast for a second and then running back inside…
…and that is how the dad has a photo of himself standing outside in the snow in Antarctica with •Wernher von Braun• both completely buck naked.
