This is pretty bizarre.

A Chinese man is claiming he went to a hospital for surgery with NO tattoo on his butt.  Well, according to him, he has a tattoo now.

The man is refusing to leave the hospital until the matter is dealt with.

As of now the hospital is claiming the man is just having an allergic reaction, to get this, BED SHEETS.  Really?

Metro.co.uk is reporting that Sheng Xianhui went in to have gall stones removed.  Well, the stones are gone and he now has a tattoo that reads "stones disease" on his ass.

It is written in Chinese so it could really be an astrological sign or read "sweet and sour #4" as far as I am concerned.

The case is under investigation.

What do you think?  Allergic reaction or permanent tattoo?
