X-Ray
As you can see here, this man actually made a tutorial on youtube about how to build an x-ray machine, after the hospital charged him just shy of seventy thousand dollars. That is a crazy amount of money and we have no idea how they even justify that. What could possibly cost that much in services?

Do the doctors give you a gold-plated hospital gown to wear while at the same time feeding you the finest food and giving you a full body massage? We really have some questions for the hospital representatives to explain such a crazy bill for an x-ray. Also, how do you build your own x-ray machine?
