I went to a school that was there simply to filter enough kids to be able to select a decent rugby team. It really was the main aim of that school at the time. Hey, none of them are going to be astronauts, find 20 that will function as a mean and cup winning rugby team.
I hated rugby, luckily for me, the 'punishment' for being a rugby spaz was to be told to fwk off over the all weather pitch with a football and entertain yourself for an hour.
