A weird x-ray from China reveals the source of a painful problem a man had in his backside.

An 8cm glass cup.

The man only told doctors what was really happening after two days of suffering but still wouldn't tell them how or why the glass was up there.

The married man had apparently been screaming for help the second he was brought in and physicians were worried about possible shattering.

Local reports said physicians tried to get it out the same way it came in, using drugs to relax him.

They were able to reach the cup but it was too slippery to get out, so to avoid the potentially lethal glass shattering they removed the cup via surgery.
