oh god, here's a terrible story from My childhood, if you don't want to read this, just skip it. It's a horrible story I would like to forget.
In my school, we had to participate in cultural events, and one of them was this asian drum thing (Pics above) and we were doing this upbeat song that would kind of make you feel like your organs vibrated, and we started practicing 2 months before the actual thing, and did it every Thursday.
Now, we had this one "special kid", let's call him Kevin. Kevin was kind of an idiot and did weird things, like once he tried to shove his phone up his asshole (wish i could unsee that) or tried to explain that NASA can create aurora borealis, but this one takes the cake. One time, we were about to finish, doing the most rhythmic part of the song, and we had to hit the drums really hard.
Everyone was basically acing it at this point after like 1 and a half months of practice, and Kevin, being him, went crazy like Kyle after his 20th Monster Energy Drink. I remember he banged the drum so hard, he had to get a new one.
In this bit, Kevin was going absolutely crazy like he got possessed. He wasn't in front, but still did a pretty big role in the performance. During practice, on that time, we were doing it thinking nothing would happen and we would go home after, but then nearing the end, Kevin tried to hit the Drum with a really hard hit, now the thing is, to move the drums, they have wheels, and Kevin accidentally moved the drum a bit forward during practice, and as he hit downward, he missed the drum, and he hit his balls.
Think of the worst scream of pain you know, now multiply that with a 10X mic and a gladiator deathfight. Everyone looked at him stunned, and basically everybody in the room kind of felt an ethereal oof kind of pain as well, and Kevin got took to the ER. he ruptured his right testicle and needed surgery, and didn't go to school for 2 weeks. just thinking back on that is painful.
