Some people think they're real enough to beat them up. Visit the Real Doll Doctor, because he has great photos and describes some of his most impressive surgeries.
For some reason, there are people that buy these things and then beat them up, butcher them, bend them into unusual positions, you name it. I guess if you're into that shit, it's better to beat the hell out of a doll.
This is one of his patients.
