This is one of the longest English sentences that is not a run-on. Or at least one of the most famous ones. You have to say it in one breath. Can you do it? (Hint: You need to put stress on the word "intentional" because he is telling everyone he's not guilty of intentional error.) Good luck. "Though, in reviewing the incidents of my administration, I am unconscious of intentional error; I am nevertheless too sensible of my defects not to think it probable that I may have committed many errors." —George Washington's Farewell Address, 1796.
