The Mary Worth (also known as Bloody Mary, Mary Margaret, etc) story is popular at sleepovers. As the story goes, a beautiful young girl named Mary Worth was in some sort of terrible accident (or occasionally the wounds are inflicted purposely by a jealous party), and her face was hideously deformed. From then on, she is shunned by other people, and she sometimes becomes a witch. Now for the scary part. Supposedly if you say Mary Worth's name three (or five, or ten... it varies) times while looking into the mirror, Mary Worth will appear and scratch your face off or kill you.
