We did all the time - scared the crap out me too!

Apparently kids these days play "Charlie Charlie" - similar to the ouija board~

"To take part, people are instructed to get two pencils and lay one on top of the other in a cross shape on a sheet of paper. They then write "yes" and "no" in the resulting four quadrants and ask, "Charlie, Charlie, are you here?" or "Charlie, Charlie, will you come out to play?"

If the top pencil moves and lands on "yes," then apparently a demon named Charlie is in your house and players can ask it more questions. "
