Life on the streets is tough. And Carl and Darren personify that.
Darren describes himself as Carl's brother: "I have been through everything that he has been through. We live together, we suffer together, and we get jumped together."
The men, both 55, are homeless and spend much of their day sitting outside Barnsley Town Hall. Listening to their stories illustrates how brutal homeless life can be.
Carl said he doesn't know how many times he's had a knife pointed at him. He counts his scars, and concludes that he has 15. That, he concludes, must be the number of times he's been stabbed, reports YorkshireLive.
Fighting back tears, Darren says he feels let down: "I am 55 years old. I have never had a council house in my entire life. We live in these streets. We eat in these streets.
"People say it is the alcohol but it is not. I can't even afford food so alcohol helps me pass out and takes the hunger away."
When night falls, Darren and Carl walk to St Mary's Church Barnsley, where the staff there allow them to sleep in the corridors or by the foyers on condition that they clean up every morning before they leave.
Darren said: "They are just about the only people that care really. They make us a hot cup of tea and let us have somewhere to put our heads out at."
Carl and Darren's bond is somewhat legendary within the homeless community in Barnsley town centre. John, 49, says the two are inseparable: "It is not just that they look alike, they are really brothers."
Carl's ex-partner is not homeless, and she allows him to sleep at her place for three days in a week, but the thought of leaving Darren means, more often than not, they brave the cold wet Barnsley nights together, and Carl says it is worth it: "Darren is my brother, he is my twin brother and everybody calls us twins here."
But there is a shocking reason how the two came to be known as twins and it has nothing to do with them being inseparable or sharing resemblance. As he gestures to his abdomen, and hastily lifts his t-shirt off, Carl says he and Darren have a bond thicker than blood: "You see this scar. This is why we are twins.
"Same amount of stitches and same injury. Scars are thicker than blood."
The scar Carl refers to, which Darren also has, is a 26cm scar which came about after a robber stabbed him and ripped his stomach open, leaving his intestines hanging. Carl said: "I was stabbed and them geezers ran the knife up my stomach."
Darren has an identical scar, which is the result of unknown muggers jumping him in Barnsley town centre. Darren said: "It was the same thing, they left me for dead with everything hanging out."
Both Darren and Carl claim they became closer after going through the same experience within weeks of each other, and they claim since then, everything seems to be telepathic between them. They even say, though this could not be verified, that they both received £6 from Universal Credit last month.
But sometimes, Lady Telepath seems to only bring gifts of misfortune to Carl, whose leg was broken in a hit-and-run last year. Carl said: "I still can't walk and have a cast over a year later. It was the one day we weren't together and look what's happened."
Yet despite all the misfortune, Carl and Darren insist they are twins, huddled together by a bond much deeper and more twisted than blood - the bond of a twisted knife that ripped their bellies open and left their guts hanging.
"We are a true Barnsley story aren't we. Like soldiers at war, our scars are thicker than blood and they make us twins!"
