Dr. Horrible

If you haven't watched Dr. Horrible, you must do so. It's a "sing-along blog"--basically a direct-to-internet musical written and directed by Joss Whedon, about an evil superhero, played by Neil Patrick Harris (aka Doogie H., aka Himself in Harold & Kumar), and his nemesis, Captain Hammer, played by Nathan Fillion (of Firefly, Serenity, and Buffy). Go, watch it now. Go!
