I'm not all the way through the episode yet (I listen while driving) but so far it hasn't really been about giant anybody. So far it seems to be about normal-sized women and tiny men, but the regular-sized women are called "giantesses" because, of course, everything revolves around their point of view.
Also that wax-effigy story had one of the most blatant author-started-masturbating-here moments I can remember hearing.
