After reading latest chapter from one of my favorite authors I looked up the full text of the original "riot act". Here are words that must spoken to use the riot act. Say it next time someone gets out of control.
Our sovereign Lord the King chargeth and commandeth all persons, being assembled, immediately to disperse themselves, and peaceably to depart to their habitations, or to their lawful business, upon the pains contained in the act made in the first year of King George, for preventing tumults and riotous assemblies. God save the King.
