It's a funny old world...
It's a funny world indeed when we mess about with foreign objects inserting them into orifices they are not intended for. I am not entirely convinced this was just a prank but you guys make up your minds...
"Muthuvatti Abdul is lucky to be alive," a spokesman for the Salmaniya Medical Complex told reporters in Bahrain, "but the damage is not irreparable and we are confident we can fix him. He is active, and able to digest normal food, and in a few days from now we will perform further surgery on his large intestine; but in my thirty years as a surgeon, I have never before seen such a case. Let this be a warning to all workers not to play jokes on each other with high-pressure air hoses."
Speaking from his hospital bed, Mr Abdul later explained how a prank at a building site near Alba had gone seriously wrong. "I had been sandblasting with my friend shams, and we were covered in sand. So we stripped off naked and turned the hoses on ourselves to clean ourselves. I was bending over when Shams inserted the nozzle up my rectum and gave me a quick blast of air. He only did it for a few seconds. It was just a joke, that's all. But I asked him to do it again out of interest. When he did, I immediately felt myself blowing up. I knew something inside was clearly wrong. So I came here to the hospital, where they examined me, and told me that the rush of air had burst my large intestine, and created an opening in my bowel. I have telephoned my family back in India to tell them I am off work, but they do not yet know why. They will be shocked when they hear the full story". 
Hmmmm.... them and me, thats for sure!
The Spokesman added that the "high pressure blast almost burst Mr Abdul's stomach, and if that had happened, it would have been impossible to repair the damage. People need to understand that these appliances are not a joke. In the wrong hands, and in the wrong place, they can kill"
