Two guys are chatting in their hospital beds;
"What are you in for?" said the first,
"Camera down the throat" the other replied,
"Oh endoscopy?" the first man asked,
"Yes" he said "What about you?"
"Camera up the arse" he said,
"Oh, colonoscopy?" quizzed the second man,
"No, my neighbour was sunbathing topless and my wife caught me taking a photo"
