I remember pulling the heads off Barbie dolls, and pulling the tails out of My Little Ponys, but I think that was more exploring the limits of their construction, and trying to see how they were put together. (The Barbie heads pop off. The pony tails have little metal things inside.) There were a few other things that I damaged, and most of them were the same impulse -- I wanted to take them apart to see how they worked, and I didn't realize that they couldn't be put back together.
