Poor Female Self Image

I found this on the back cover of the Sun Herald yesterday. (Sunday 5th June 2011).

Taking photoshop and editing too far .... How skinny DOES she have to be?
Skinny enough to dissolve her knees.  Really, look closely, she has no knees.

It's still blatently obvious that a normal human figure is repulsive on the cover (or back) of publications.
What's wrong with knees? I assume she has them, but I cannot see her patella, her knee dimples ... nothing.
