So, a long time ago, I read this Sandman comic that told a fictionalized version of the story of the Emperor of the United States, a real-life character straight out of Twain (to the point that Twain based a character in Huckleberry Finn after him). I was fascinated and delighted by the oddness of it, and wanted to find out more - but libraries and Yahoo failed me, so the thirst for more knowledge went unquenched.
Today, I was reading an article on Neil Gaiman's site and saw a reference to the Emp - figuring that it wouldn't hurt to try looking again, I Googled "Emperor of the United States"... And found him instantly!
I love Google so much. My friends make fun of my eagerness to look stuff up online - but that is because they fail to understand Google's amazingness.
