This has to be the coolest thing I've ever seen on the Internet. I'd heard about it over the past few weeks and was mildly amused at the idea, being a Firefly, Nathan Fillion and Joss Whedon fan. Heck, I'm even a Neil Patrick Harris fan to a degree after watching Harold and Kumar Go to Whitecastle. But I didn't really think I'd watch the thing. I've now watched two of the three parts and this thing ROCKS!
All three parts are available for free until midnight Sunday, afterwhich you'll still be able to get them off itunes, but not for free. Eventually there's suppose to be a DVD, but I'm guessing they might charge for that.
Anyways, go see this. Now. I mean it.
