Send them to Jamie's dream school.
Actually we should build a school specifically directed at yobs. Let's call it "Yob School".
In Yob school there is a very refined social hierarchy. So refined, in fact, that there is actually a huge board outside the school displaying where exactly each person is in the pecking order - because this is all that matters.
The pecking order is determined by fighting ability and general don't-give-a-f***-attitude. You match this, you reach the top and get all the babes.
At the end of the year you fight it out with each and every one of your classmates for your GCSE's. If you succeed, then you're lucky enough to get a solid punch in the face by a headmaster! Everybody's happy!
