The latest Internet obsession appears to be a game called the “Charlie Charlie Challenge.” The game consists of two pencils balanced on a sheet of paper and has a “Yes” and “No” written on it in a simple grid.

When someone says “Charlie, Charlie, are you here?” they wait to see if the pencil turns to “Yes” or “No” to try and summon the alleged Mexican demon.

Like any other Internet craze, the game has gone viral on Twitter and people are sharing their videos online and showing their reactions to the pencil movement. It has its own hashtag #CharlieCharlieChallenge.

Here are some of the funniest videos and tweets about the Charlie Charlie Challenge.
