Hope this isn't already in the list, but when you go to the one Elementary School that's relativly near to the start of the game, you walk in to find the place crawling with raiders. Then you go searching and find a nuka-cola QUANTUM! Yay! Look underneath where the Quantum is, and la-dee-da there's a CAGE with CHILDREN-SIZED skeletons.
I'm all for the caging of children in a post-apoctalyptic wasteland whilst they enjoy their lessons. :D
