Sarah Palin also happened to be attending. Ms. Palin took the
opportunity to schmooze the good doctor a bit and asked him a question
with which he was most at ease.
"Would you mind telling me, "Doctor," she asked, "How do you detect a
mental deficiency in somebody who appears completely normal?"
'Nothing is easier,' he replied. 'You ask a simple question which
anyone should answer with no trouble. If the person hesitates, that
puts you on the track.'
'What sort of question?' asked Governor Palin.
Well, you might ask, 'Captain Cook made three trips around the world
and died during one of them. Which one?''
Palin thought a moment, and then said with a nervous laugh, 'You
wouldn't happen to have another example would you? I must confess I
don't know much about history.'
