I might ask him if he possesses the cognitive functional ability of Abstract Thought, because he seems to give the same 10 cookie cutter, rote memory responses to every question, you can almost see his brain motor turning as he is searching for the prerecorded answer that best fits the question.
If he responds without using the terms "stacking days", "each and every", "as I said", or "we'll look at the tapes", yet continues to evade the question in a more creative fashion, as he most likely would, I might ask him if he has ever considered going into politics.
