I built my Medieval Market Village last night and despite having no trolls or skeletons in it whatsoever it is an AWESOME set.

Unfortunately now that it is built I am very convinced that I have a missing piece. I've never had a missing piece from a lego set ever, what is the best course of action? I don't feel like dismantling the whole damned thing and returning it to Target on the account of a single 1x1 brick and its not the kind of piece that can be left out without looking glaringly bad. Well... thats not entirely true, I could do the i-pod shuffle.
