When you have paid your fee, there is a series of challenges that you have to pass before you can even be considered to be promoted onto the main roster. Nothing to wierd. You have to pick up a penny in your arse cheeks and drop it into a glass. Then there is the 'barbed wired thong' challenge, which is always great fun to watch.
Then you have to joing a club that you're not allowed to talk about (dems da first two rules, you see!). If you survive it in there, you will have become a Jabe.
