606V2 Tough Enough

This thread should probably be in the sports gaming and betting thread, but I put it here anyway.

I am not too familiar with tough enough or indeed how it works, as I have never seen it. However, I was thinking we should have our own version of tough enough on this site in parallel to the WWEs show involving our own posters. What I would like to know first is a brief summary of tough enough and it's usual structure and secondly if you would like to take part.
