Snapped my femur in a motorbike accident when I was 14. Seriously one of the worst breaks I have ever seen, on tv, internet or otherwise. Would have loved to have a photo of my lying in the ditch with my foot up next to my head. I also had a piece of fencing wire go through my shoulder, and inch or 2 to the right and it would have pierced my heart. I was lucky enough to recieve some new experimental leg pins which saw me only spend 2 weeks in hospital, rather than the 3 months in traction which was the alternative. Depsite the pain, the limp, the hospital time, the physio, etc, it wasn't a bad deal for a 14 year old, getting a term off school to play his new Nintendo 64 in a recliner at home haha.
Other than that I have broken my big toe playing on machinery as a teenager, and my little finger when it got jarred by a basketball.
