For randomness. A poster inserts a coin, and the person below states what the previous poster gets. Then he inserts a coin of his own and on it goes~
Random Person 1: *inserts coin*
Random Person 2: Person 1 gets a bonk on the head. *inserts coin*
Random Person 3: Person 2 gets a scream. *inserts coin*
Random Person 4: Person 3 gets a smelly pink sock. *inserts coin*
Time to start.
