As I was heading into work today on the Go Train and flipping through the contents of my iPod, I found Dr. Horrible's Sing-Along Blog. I had forgotten that I had downloaded this so it was an unexpected treat to come across it. It's basically a short musical created by Joss Whedon, the brilliant mind behind Buffy the Vampire Slayer, that was distributed solely on the Internet. It's clever and funny and very entertaining. I highly recommend checking it out, especially if you are a Neil Patrick Harris, Buffy or musical theatre fan.
