A book on Scandinavian Humor had a cold-scale based on obscenities used to describe it. From 1 to 3.
1: **** it's cold out.
2a: **** **** it's **** cold out.
2b: **** it's cold out. *****
3: ***** **** it's colder than a **** **** out there. ****
Most of the US is plunging into 2-obscenity cold in the coming days, with 3-obscentiy cold at night.
