Well we were all kind of very drunk and that pretty much explains the whole story.
But basically it started with a game of Halo multiplayer at a party. Somehow a tickle battle erupted and clearly the best course of action was to steal a friend's shoe and run away with it. Of course he caught up to me being the speedy ultimate frisbee player he was and tackled me outside and I landed on my shoulder with an extremely audible crack. We didn't figure out something was wrong with my shoulder until a few minutes later and even then I just kinda laid on the floor in someone's room hoping to feel better. Another friend had just finished some kind of forestry first aid class thing and she was all excited to try it out on me so I ended up getting all wrapped up in strips of various types of cloth. Ended up going to the ER after about an hour or so and getting xrays. Snapped my collarbone right in half! I couldn't wear tshirts for a month because it was too painful to put them on. Super annoying. Also I learned they don't do anything to treat broken collarbones, just give you a sling and instructions to wear it for a 6 weeks. Grossest part was for the first few weeks I could feel/hear the bone grinding on itself as I went around my daily business.
Yeah he did. The ER doctor commented that he "must have been a huge guy", but really he was pretty scrawny. Athletic, but very thin. I met his mom at graduation and should have said 'hey your son broke my collarbone, did he tell you that?' Haha!
In high school, a friend of my broke his collarbone freshman year. His first day in school after that, doped to the gills on pain meds, we had an exam in our history class. The teacher offered to let him take it later, but he said he was fine. Apparently he did the map (of Europe!) upside-down, and it was downhill from there.
