I think Scott's point is to continually answer them with a question, thus negating understanding & surety:
eg: Why would I want to do that?
Are you offering me legal advice?
By what authority are you offering me legal advice?
Are you attempting to make me surety in this matter?
What evidence do you have that I could be such a thing as surety in this matter?
How can I possibly assist the court if I'm not able to establish the facts of the matter?
etc etc...ad infinitum
and the favourite: Who ARE YOU?
