A Bloody Joke

A man named Kevin died in his own room, he was burned to death, so it's hard to recognize.The sheriff asked his friend Craig whether he could tell this is Kevin or not.Craig turned Kevin's darked body over and say : "No, this isn't him." The sheriff asked : "why?" Craig said : "Because Kevin has two assholes." The sheriff was shocked, but he said nothing, and he asked another friend of Kevin, Jack, to recognize the body.Jack did what Craig did, and said what Craig said.The sheriff was really confused, he asked them : "This is Kevin, isn't it?" They answered : "No." He asked : "Because he has two assholes?" They answered : "Yes." He asked : "How come?" Craig said : "Well, each time when we went to the pub, the townspeople always say: 'Lo, there comes Kevin with two assholes.'."
