Justin Born's Final Project Dr. Horrible's Sing-a-long Blog. Poor Billy Buddy, aka Dr.Horrible, is shy, unimpressive, awkward-the proverbial geek.  And as it goes with all social rejections there is a beautiful, kind woman that is always just out of his reach and in the arms of the charming, gorgeous, talented jerk- the bully.  It's the tale as old as time told with a fresh new twist.
