So, one time when i was little. I was super into God Of War for PS2 and little me decided it'd be fun to jump off my trampoline with a wiffle bat in my mouth (There was an attack were kratos would hold a sword and his wouth and jump down onto and enemy), i did this and it hit the back of my mouth, cutting my uvula and making me bleed like hell. i was in the hospital for hours.
I healed up and everything's been fine since.
