Dang, the votes really are getting spread out.
Rush, I agree that Profit and Lace isn't the worst of DS9. In fact, my choice for the series' worst didn't even make it onto this list (Let He Who Is Without Sin...).
And, I think Profit and Lace is a fairly average episode, probably around a four or five out of ten, up until the point Quark becomes a woman. Then it just nosedives, IMHO.
