There used to be a famous biscuit company in Australia called "Arnotts" which was taken over by an American multinational in the 90"s. They had and may still have a biscuit called the "Sao". From about 1979 to 1985 teenage high school boys played a game called "Soggy Sao". They would place a Sao in the middle of a room and stand around at a certain distance and engage in a certain activity to prove their sexual prowess and virility. The person or persons who could directly hit the Sao would win. Now I assume that more than a few of these competitions took place on carpeted floors. I would certainly avoid carpet if I knew such activities had taken place.
