Now I wouldn't. Like Murf, I did play around with it a little when I was a kid, as did a lot of my friends. We would hold "seances" and we would try to summon "Mary Worth" but as I got older, I started having serious reservations about that sort of thing. My religion, as I found out later in life, forbids it to boot, so I stay away from seances and the like.
Here's the real kicker, though. In order to summon "Mary Worth," you had to stand in front of a mirror with two candles lit, lights turned off, and with your hands up like you were swearing an oath, and say "I believe in Mary Worth" 7 times. All of us have tried it, but none of us EVER got to number 7. Only one of us, my friend, got up to number 5. All of us would chicken out after saying it 4 times. According to legend, if you said it 7 times, her image would appear in the mirror, and she would kill you.
I STILL won't say that 7 times in front of a mirror. In fact, I won't even allow others to hold seances in my house any morel
