I nearly left my spine in Snowdonia
I was on a 6th Form Geography field trip in Snowdownia. We'd stopped the minibus to eat our regulation hostel sandwiches in a place with lots of hills, grass, sheep and rocks - quite a familiar sight by this point.

Being the attention whore that I was, I decided to show my fellow geographers my ability to chain multiple forward rolls together to create a "human cannonball" effect. I located a hill that didn't have too many rocks (oh and those small black balls of sheep poo), shouted "watch this!" and off I went, floundering like some awkward panda. After about 6 rolls I stopped and stood up, my classmates decidedly unimpressed.

Walking back up the hill I noticed something. About a foot away from the path I had rolled was this smashed, glass fish tank. About two feet long with lots of jagged glass shards pointing upwards. I stopped, paused to think exactly how they would have airlifted my twitching, bloodied body out of the mountainside, and vowed never to do it again.
