I've recently been binge-watching Batman because, you know, I've got some time, and I've been admiring the fabulous Batcave. Wouldn't it be cool to live in one of those if it had all the modern amenities?
Well, apparently if you have a few million dollars you absolutely can. This house that was for sale in Parthenon, Arkansas was built in an actual living cave and it looks totally mind-blowing.
