I once drove two medical professionals, and one of them was talking to his colleague about the time he was 'kindly kidnapped' out of the hospital by two guys who took him to a mansion outside of the city. There, they asked him to examine the heart condition of a man who seemed to be a local mafia boss who was wanted by the law.
They somehow provided him with all the tools and help, and made him operate on the boss. Then they finally let him go, paid him with a big sum of cash, and said they would contact him again for anything else. He said it was one of the scariest, yet most interesting experiences in his life.
