A couple of days ago I read a story about how an outline of the Virgin Mary appeared on a food griddle at a restaurant on the California/Mexico border. The faithful and the curious are flocking to see it. (You can read more here.)
As I recall, the Virgin Mary has previously appeared on a grilled cheese sandwich and on a pizza pan.
I must admit that I personally don't really see the Virgin Mary on the griddle (or grilled cheese or pizza pan) without using my imagination to some degree. Not like the appearance of Presbygal in my breakfast this morning. That was straightforward.
