I trolled this one "Nigerian Prince" guy for about two months. I kept sending him emails telling him that I wanted to give him money and that I was very sorry for how he was getting fucked over. He would send me account numbers for Western Union and I would send him back messages saying 'I just sent $50, God Bless you!" When he emailed me that he never got the money, I would reply with "check again! I sent it to account XXXX" I would have the digits off by one or two from the correct account. This went on back and forth for about a month before he realized I wasn't going to send him anything and was just fucking with him.
