Meanwhile in Finland

This is Finnish humor: A guy is buried in a snow pile, in his swimming trunks. The other guy pretends to be a host for a nature document and disturbs the sleeping creature. The guy from the snow pile "wakes up" and goes into the freezing cold lake for a swim. Once the guy gets out from the water, instead of going to a hot shower or a sauna, he goes back to "sleep" in the snow pile.

You can see that there are also other people going for a swim at the same time. That is because winter swimming in a freezing cold water ("avantouinti" in Finnish) is an actual hobby for some of the Finns. There are public places where the water is kept unfrozen with water pumps and possibility for a shower or a sauna is arranged.
