So You Want to Win a Challenge? And it's come down to your Hail Mary option - asking that Scottish-Italian arsehole Paul Stewart, how to do it?

That seemed vitally important to my Sensei, and so I must impel you to learn it as I did. If you don't have karate pyjamas, just wear clothes. Any old clothes. Yep, even the one with the curry stain.
