We denizens of this site quickly saw our lovely leader C.C. in the gimmick of double C's in each two word phrase where the first word ends in C and the second word begins in C. However, John's fine hump day offering invoked the original use of CC for the Carbon Copy method of producing a messy facsimile as seen in this blurry CC of an interesting 1958 typewritten letter from Eleanor Roosevelt to JFK.
Today, of course it is mainly used as a way to send a duplicate email to another recipient electronically sans the messy paper
