Replying to Worst injuries you've had or seen

I have never been hurt bad myself, just stitches. I once saw a kid in my class break his leg playing football, and he was just lying on his stomach with his leg hanging at a 90 degree angle. Another bad one i witnessed was when i was biking with some friends and one went to hit a drop and when he was in the air a stick got caught in his front wheel and he went over the bars and faceplanted hard. he ripped his braces right off his teeth. So yeah lets hear some stories
