Because why not? Any story you have about being stupid and getting mild injuries. For example I was once an overconfident fool in the ring. Tried to go for for a high kick, thought I was fast enough, my opponent just gave the good old elbow slam and nearly broke my foot. Ow, ow, ow.
Or once, I was trying to pull a lollipop out of a moustrap using two matchsticks…One of them rubbed along the ground too much and set my sweater on fire and burned my arm a little.
