And in that same class, we were dissecting owl pellets. The teacher gave us a tray with all sorts of tools. My friend and I were paired up and he saw the scalpel and started playing with it. He pulled the sheath off of it, and then the teacher told everyone to not touch the scalpels until she spoke about them (not seeing that he was already touching it). He put the scalpel below the desk while in his lap and slowly reinserted it into the sheath and thats when his eyes went anime. I looked at him and wondered what happened, then he put the scalpel back on the tray and thats when I saw the tip of the scalpel was sticking through the sheath by a good quarter inch.
Turns out, he put his thumb over the end of the sheath and pierced himself. We tried to stop the bleeding, but after going through a box of kleenex in less than a minute, the teacher caught on.
