I was jumping on a trampoline with my nephew, and his best friend (Wich at the time was much taller than both of us) and we were having fun, at the time. (This was several years ago) I eventually get launched up, at one point, way over their heads, and the next thing I knew, I had landed on one of those coils that held up the trampoline, I landed on my crotch. I gasped in pain, and attempted to get off of it, it started ripping my pants open, the next thing I know, I'm bleeding all over my leg, I eventually got off of it, and rolled over on the ground, I couldn't walk, so my friends had to carry me back to the house.
