From a free book I got when I read at a laundromat with Sung J. Woo

"In 1404 King Taejong fell from his horse during a hunting expedition. Embarrassed, looking to his left and right, he commanded, 'Do not let the historian find out about this.' To his disappointment, the historian accompanying the hunting party included these words in the annals, in addition to a description of the king's fall."
