The only criticism that I have is that when you ask a yes or no question you need it to ask it again and again and again, if necessary, if the person is evasive.

I once saw this on a British interview show. The interviewer probably asked a British politician the same question 10 times in a row.  Absolutely refused to accept the dodge.

The brilliance is that the audience totally gets it.  They might not pick up on an artfully evasive answer the first time, but after the 3rd, 5th, or 10th time, they get that the person is a weasel.
