As these x-ray pictures show a Romanian man had a heavyweight way of dealing with a bad case of constipation.
Viorel Firoiu, 48, turned up at the local general hospital in Orlea, southern Romania, complaining of incredible abdominal pains.
Doctors who carried out an x-ray of the man were amazed to find not one but two hammerheads stuck up his backside.
Dr Cristina Bontescu, spokeswoman for the local hospital where he turned up at the emergency unit, said: "He was a bit drunk and said he had been eating cherries that had left him badly constipated. He said he had a few drinks to dull the pain and then came up with the idea of poking a hammerhead up his backside in the hope of sorting out the constipation.
"But the hammerhead got stuck and then he came up with the idea of using a second hammerhead in order to try and get out the first – but then he lost the second one as well."
Doctors had to perform surgery to remove the two hammerheads.
