I think it's interesting that in conceiving "nasty" icons, the images are almost entirely either violent or scatological, rather than sexual (the bare-breasted woman being the only exception I noticed). I imagine a few possible explanations: a) the creators considered sexuality too risqué for what they were doing, b) they considered it not nasty at all, or c) the emphasis was on a childish nastiness, rather than a grown up one.<p>It may speak to the relative acceptance of violence vs sexuality in our culture?
