15. “Prussian Exercises” let people scream silly things at their friends.
A group of people gets together while one person pretends to be a drill sergeant. They start to scream at the “cadets” to do certain things, and they have make up the most ridiculous commands possible. The cadets try not to laugh, and keep a stony serious face. If they burst out in a fit a giggles, it means they are out of the game. After a while, if the remaining players get bored or they really just aren’t going to laugh, they get down on their knees and the drill sergeant knocks them all down like a line of dominos. If there was one winner, they could become the drill sergeant in the next round.
