Well in 7th grade I was sitting next to a kid in class that kept -blam!-ing around with his chair. Rocking it side just because we were bored shitless. This was a one piece desk and chair that had that hard risen tops and desk that were blue and gray. Well he went too far at one point and the whole weight of his body and desk fell on his middle finger. It crushed his last knuckle on his finger and blood jumped up his desk and almost hit the ceiling. I saw him fall and the blood jump up. The cry and the trail of blood from our classroom at the farthest part of the school to the nurses office was horrifying. After a few surgeries he lost the last knuckle I believe. It was funny when he flipped people off.
