The Virgin on a turtle's belly

But I thought the world was carried on a turtle's back?

Shirley McVane of south suburban Burbank has had two pet turtles for about a year. But it was only recently that she noticed something different about one of them. McVane says a turtle began to develop what she believes is an image of the Virgin Mary on its shell.
"I told some of my friends, you know, 'I got a turtle,' and I said it has the image of the Virgin Mary on it, and I said it's getting plainer and plainer, and they said 'Yeah, Shirley, you're 81 years old. You think we believe that?' I said it's the truth, so now they all believe it," said McVane.

McVane has since renamed the turtle "Mary" and its tank mate "Joseph."
