Is this love that I'm feeling?

Oh my goodness, this news from the entertainment world makes my frankly frivolous pop culture heart go pitter-pat: Joss Whedon is doing an online musical starring, among others, Nate Fillion of Firefly (and Desperate Housewives, but who really cares about that? And also that short-lived cross-country road trip show that no one watched but me). Remember the Buffy musical? Come on, you know who you are, you small sliver of my tiny readership, you know you totally remember and have watched it multiple times since. Aren't you excited??
