Dr. Horrible won an Emmy (although they don't air for another week, the ones that don't get air time have already been announced!) Although Buffy got shafted before Joss is being recognized for the wonderfulness that is Dr. Horrible.
If you haven't checked out Dr. Horrible, you should. Dr. Horrible is a great musical staring Neil Patrick Harris as the lovable Dr. Horrible who wants to rule the world and get Penny to fall in love with him. Captain Hammer, the "hero" of the story, stops the Dr. from only one of these.
AND NEIL PATRICK HARRIS!!!
