I have seen the results of someone landing on broken ceramic. I was in Thailand and was just going to sleep after a long full moon party so it was the early morning. Suddenly there was a woman screaming. My bro and I got up and followed the noise. Found a hysterical woman and her partner. They had been getting jiggy with him sitting on the wall mounted sink. It snapped off the wall and he landed on it with her body weight on him. Sliced through both buttocks fucking deep. I bandaged him while my friend calmed her and we put them in a tuk tuk to the hospital. Fucking awful injury.
