My brother told me once when he was in high school he was playing with a stapler. And he took all the staples out and thought ‘I wonder what will happen if I just.
” then he stapled his thumb and turns out there was still a staple in there and he impaled his finger. The whole thing went in.
Our mum was a doctor then so Since he was in his last period he was just gonna wait.
So for about 15 minutes he just kept his hand under the table till the girl next to him saw the puddle of blood and screeched. So he had to go to the nurse and he was grumpy the whole day
