You, Tsuki and Tsuki's friends had been playing baseball, but after a couple games, they found a stretchable hose. They guys started playing tug-of-war with it while you sat and watched. Tsuki turned, picked up his water and went to take a drink when the opposite team let go of the hose. It came flying back and hit Tsuki in the back of his head causing a huge gash and Tsuki to fall to his hands and knees
