First off, I think Lenny is talking about soccer, second i have broken a kids arm before in a fight and broke a kids shin in soccer (Accident).
Myself, i broke my collarbone in 11th grade when i went snowboarding for the first time. My friends led me down a black diamond and i hit a patch of ice and went flying down half the mountian. After i stopped rolling, i stood up and noticed that my arm was completely behind my back, some scary shit. They had to knock me out to fix it but thankfully i didnt need surgery. Spent 3 months in a sling and got some awesome pain meds. I was flying high for a while
