Pick any oneshot or chapter of a fanfic I've written, and comment to this post with that selection. I will then give you a DVD commentary on that selection: what I was thinking when I wrote it, why I wrote it in the first place, what's going on in the characters' heads, why I chose certain words, what this chapter means in the context of the rest of the fic, lots of awful puns, and anything else that you'd expect to find on a DVD commentary track.
