LOL how the actual stuff did that happen Rolls
We were standing on a concrete circle with a line painted down the middle. The discus thrower was on one side of the line, and all the spectators, including myself, were on the other. The only trouble was, the girl throwing it (yes, it was a girl, Lucy-Anne Noontil), spun round and round to pick up momentum like they do at the Olympics, became discombobulated, and turned around and fired it over the "safety" line straight at the spectators, where I was lucky enough to stop it with my face.
I was also lucky enough not to be knocked out cold (goody), and had the pleasure of being conscious all the way to the hospital in the back of the maths teacher's van.
