Having a tangled chain in your bladder must be painful
There are a lot of holes in the human body. But even if they are open, this does not mean that you should try to stick anything inside of them. Especially when the hole is as tiny as the urethra. And even more so if you are trying to put in a chain.
Let this be a lesson for all people that want to attempt something similar to what this man did. Not only will a herringbone gold chain passing through your urinary tract hurt a lot, but there is also a big chance that you will end up in the operation room.
