I would like to add that they do take a pretty girl, expose her to the worst possible lighting conditions, and then subject her to hours of torture (you can really see it grate on her when they work on her hair) so the transition from "pretty girl" to "hideous frog" to "makeup model" does make the contrast seam sharper. However, I think the photo editing makes the chick look CREEPY! Like lowering and stretching out the eyes? *shivers*
Of course, it is an anti-advert-advert, so maybe they did that explicitly to put people off.
