I've just wasted a good chunk of my Sunday afternoon watching this show, and you can too... at least until it disappears and can only be found on iTunes (which I found out today is entirely unavailable for Linux).
If you were ever a fan of Joss Whedon, Capt. Tightpants, er., Nathan Fillion, or the incomparable Neil Patrick Harris, go watch. Now. Then laugh. Heartily. Or at least evilly.
