People often obsess over weird things, and in this case, the weird thing is manhole covers. Yes, the things that allow city workers access to sewers and other underground systems.

People from all over the globe are travelling to Japan to get their on collectable "manhole cards" (which, let's be real, just sounds dirty). Why are they so obsessed? Apparently, Japan has some of the most ornate and intricate manhole covers in the world.

We're all about people being into whatever they're into as long as it's safe and legal, but this one just seems boring. Even the reporter can't muster up much excitement about it.

Is this something you could get into?
