Ever dream of becoming Supreme Dicatator for Life? Who hasn't, right? Heh heh heh...anyway, if you have any aspirations at all of someday ruling the universe, or some substantial chunk of it, you absolutely have to read The Evil Overlord List. In fact, if you just happen to watch or read sci-fi and/or fantasy, you will spend a sizeable chunk of time giggling maniacally over this list, and the two lists that branch off from it.
Cowboy also linked to this, but there are several people (Lanyn, Lily Snape, Freestargirl) who read this and probably don't read his blog, but who will definitely enjoy the list :-D
