One day Chou and a friend were leaving a restaurant after a meal and saw a coin-operated scale outside. When Chou stepped on it, the scale's computer told him: "Child, you are 163.4 centimeters tall and weigh 39 kilos. Best wishes."
為此，周公說了個笑話：一回和朋友聚餐完走出飯館，旁邊正擺著自動投幣磅秤，因為好玩站了上去，電腦話說了：「小朋友，你的身高 163.4 公分，體重 39 公斤，祝你愉快！」
