- SCP Foundation: SCP-3922 is a cylindrical object, when placed close to a TV set or computer, it will alter the contents of any fictional video footage playing in them, usually adding "actors" in padded combat uniforms and gas masks. These actors will prevent and punish any crime committed by the cast of the original footage. In one testing log, researchers tested it with episode 1 of the series, the actors arrested the Announcer for forcing the cast to do the challenge. Flower and Blocky were also arrested for murdering the other characters.
