Has anybody heard of this dumb Charlie Charlie Challenge?

At school, everybody was talking about it. Some things were said and it was dumb, but some had some funny opinions on it.

My friend set up the paper/pencils and wrote the yes' and no's.
He then had a chicken sandwhich from lunch, and said, "Charlie Charlie, will I eat this sandwich?"
Then the pencil moved to no.
Then he ate it, and threw out the paper. xD
