S3·E1 No Laughing in a High School

Matsumoto, Yamasaki, Endō, and Tanaka are punished after losing another Russian Roulette style game where they shocked themselves. This time, they are sent to 'high school' for one day. The punishment weapon for this game is the shinai, and Hamada participated as one of the hang-men, frequently delivering a strong kick along with the regular punishment. It was revealed that this game was shot during Matsumoto's birthday.
