Urban Legend has it, that if you go into a bathroom at night, or any room with a mirror and no light.. you can call upon the Virgin Mary, crying blood. The way to do this, is turn away from the mirror, and chant "Bloody Mary, Bloody Mary, Bloody Mary" (the three times is important).. then face the mirror.. you will see <"miss immaculate conception" herself> an unpleasant apparition.
