The Pak Ou Caves, as I understand/misunderstand it, are where people discard their unwanted Buddha statues. I’ve never thought about it before, but I can see how disposing of The Enlightened One could pose a problem. You can’t just toss him into the trash with the coffee grounds. The caves, a sort of divine retirement home, offer a nice solution for discarding of a deity.
