Two ways about it
Finns are always talking about how much the cold doesn't bother them, while Russians refuse fuck around with it.
I once traveled in the winter with a group of friends. Most of us were just wearing a winter jacket, but the one Russian wore no less than two woolen sweaters and two thick jackets, wrapped a scarf around his head and put a hat on top.
6th January 2016
Weather effects in Finland and rest of the World:
+15c Spanish wear caps, gloves and winter coats, Finns are sunbathing.
+10c French desperately try to get their central heating on. Finns plant flowers.
+5c Italian cars won't start. Finns drive with convertibles.
... 0c Pure water freezes. Water in river Vantaa thinkens a bit.
-5c First people are found frozen in California. Finnish midsummer festival ends.
-10c Scottish turn the heat on in their houses. Finns start to use long-sleeve shirts.
-20c Swedes stay indoors. Finns are having last barbeque before winter.
-30c Half of the Greek people have frozen to death. Finns start to dry their laundry indoors.
-40c Fake Santas are moving to south. Finnish army cancels winter training due to warm weather.
-50c Daninsh people are loosing their teeth. Finns rent movies and stay indoors.
-60c Polarbears evacuate North Pole. Finnish army starts its winter training.
-70c Siberian people are moving to Moscow. Finns are furious since the Koskenkorva can't be stored outdoors anymore.
-273c ABsolute Zero. Finns admit that it is quite cold outside.
-300c Hell freezes over. Finland wins soccer World Cup.
P.S. Personally I feel that in the last remark it would've sufficed to claim that Finland qualifies to the competition. Then again, according to the logic of the joke, other people probably would have perished already, so the win would be inevitable.
