My dad used to work in a juvenile detention center in the Miami area in the early 70s. He said there was one inmate that reminded him a lot of a young Hannibal Lecter. He wasn't strong but he was smart and very persuasive. One day he started a riot in his block of cells, just by talking the other inmates into it. My dad and another guard were sent in to check it out an try to calm things down. Everybody in the block was going crazy, banging on the bars, howling and yelling at each other. Everybody except young Hannibal Lecter. He was standing still in the middle of his cell with his arms folded, smiling and muttering the same phrase over and over, quietly. My dad tried to focus on what he was saying, and after a couple seconds he understood. The inmate was reciting my dad's home phone number. EDIT: I don't know how he got it. Maybe he bribed another guard into getting it for him, or he saw it written on some form on his way between rooms or something. The guy never called my dad, in fact he never really got any strange phone calls ever. But the level of determination this inmate must have had, all just to freak my dad out, was simply impressive.
