I won't link any examples for fear of kicking off some powerful nightmares, but the most horrifying postwork I have ever seen in my life was when I stumbled across a site for child pageant photos. (What I had been looking for prior to that I don't even remember, as this site truly did scourge it, and just about everything from ages three to five, from my memory immediately.) They offered a list of retouching services such as "add doll eyes" and "tear removal". I really wasn't kidding about the nightmares. Really. Not even just a little bit. If you have strong google-fu and a stronger constitution, search around a bit and you'll eventually find examples, I'm sure. It struck me as hilarious that so many people working with 3D images are working so hard to achieve photorealism, and these photographers were going just as far out of their way to avoid it, though, that's for sure.
