San Francisco has actually had its own Emperor.
Joshua Abraham Norton came to San Francisco to make his fortune, and lost it in commodities speculation. After disappearing for a while he came back to town in 1859, laying claim to the title Emperor of San Francisco.
Wikipedia wrote:Though Norton received many favors from the city, merchants also capitalized on his notoriety by selling souvenirs bearing his name. "San Francisco lived off the Emperor Norton," Norton's biographer William Drury wrote, "not Norton off San Francisco."
Norton had no formal political power; nevertheless, he was treated deferentially in San Francisco, and currency issued in his name was honored in the establishments that he frequented. Some considered him insane or eccentric, but citizens of San Francisco celebrated his imperial presence and his proclamations, such as his order that the United States Congress be dissolved by force and his numerous decrees calling for the construction of a bridge and tunnel crossing San Francisco Bay to connect San Francisco with Oakland.
On January 8, 1880, Norton collapsed at the corner of California and Dupont (now Grant) streets and died before he could be given medical treatment. According to the San Francisco Chronicle, upwards of 10,000 people lined the streets of San Francisco to pay him homage at his funeral. Norton has been immortalized as the basis of characters in the literature of Mark Twain, Robert Louis Stevenson, Christopher Moore, Morris and René Goscinny, Selma Lagerlöf, G.S Denning, and Neil Gaiman.
Emperor Norton printed his own scrip, which was accepted by many local merchants.
I could see a similar end for our previous President. I think it's more likely he'll become Emperor of the Home Shopping Network.
