...is not always the "truth". Now that Ralph Lauren has finally apologised for its cock-up regarding photomanipulation though from the sounds of it they haven't apologies for the abuse of the DCMA which does not cover these situations (fair use), for the purposes of education and posterity I along with thousands of others, a few major search engines and media outlets will preserve this for posterity and draw attention to other "Photoshop abuses".
As Blogger removed the original post because they caved in to a DCMA thread, hosting site Boing Boing didn't. Click here for the picture in question; and the picture (used under fair use rules).
Humans generally don't have heads bigger than their pelvis...not even Barbie make that bad a mistake.
Anyway, to start, Photoshop Disasters contains many of these, and here's the article about the Ralph Lauren case. Which a few news agencies picked up and and made their own exposes about this, such as ABC about the Ralph Loren picture and a minor touching up of a photograph to remove a bump. A few more from Art Threat about the Ralph Loren picture and a collection of 50 more from Graphic Design Blog.
