I bet that title caught your attention. I know it caught mine when I saw the article.
Shane Willis, an Australian burglar, had a rather unusual M.O. After robbing a house, he would grab the homeowner's cell phone, take a picture of his genitalia and then send it to everyone in the phone's contacts.
Eventually, police raided his home and found numerous stolen goods. He was later identified by his victims in what is believed to be the first ever penis line-up. (OK, I made up that last part.)
