If you're looking for a fun way to waste time, try this:
Akinator, the Web Genius. It's one of those 20 questions games where you think of a character, and the computer tries to guess it based on your answers to the questions.
So far, it's guessed Christian Kane, Joe Flanigan, Major Lorne, Spike, Tycho Brahe (16th century astronomer), Ernest Hemingway, Temperance Brennan, my teddy bear, Joshua Lawrence Chamberlain (Civil War soldier), Eddie Vedder, and the Keebler Elf.
I did stump it with John Winthrop (Puritan leader) and Ivan the Great (Grand Prince of Moscow).
