I’m a big Joss Whedon fan, and this is his latest creation: Dr. Horrible’s Sing-Along Blog.  It’s a lot like the musical episode of Buffy, but with Nathan Fillion and Neil Patrick Harris.  Check it out if you get a chance — it’s good stuff.  And the freeze ray song is still stuck in my head after watching it a few days ago.  Curse you and your clever writing, Joss Whedon!
