I have a Serenity pin on my backpack. It's actually led to more conversations when I travel than anything else I carry with me. I've gathered enough evidence from enough places to say, with no embellishment, that cancelling Firefly was a crime against humanity. And if it isn't universally regarded as such, I'll edit Wikipedia tonight to make it true.Both of these quotes can be found, of all places, on the D&D forums at wizards.com.
Special thanks to Gideon Lydiard for pointing this out to me.
