Don't know if anypony noticed or cared, but I changed the fic's name from "Carnival of Chaos" to "And I was having such a nice day" (note my very clever use of a classic Ninth Doc quotation; truly the wit stands out here :P).
While the first one was made to fit a general naming pattern I noticed in DW episodes (namely "the X of Y"), it always struck me as a bit bland and uninteresting. Make no mistake, this is a move meant to attract extra viewers, feedback and comments.
