"Mary just walked in matter-of-factly and announced that she was pregnant again. When I asked who the father was she again said. 'God,'" Joseph wrote in his autobiography Jesus and Me. "I can't pretend I wasn't a little suspicious. I mean, it's a convincing story, but I still had little doubts nagging at the back of my mind. My mate Rob said that his burd Shelly had got pregnant off that God fellow too, so I sort of went along with it."
