Department of explanation and clarification:
(later, still Palin):
"Part of Paul Revere's ride — and it wasn't just one ride — he was a courier, he was a messenger. Part of his ride was to warn the British that we're already there. That, hey, you're not going to succeed. You're not going to take American arms. You are not going to beat our own well-armed persons, individual, private militia that we have. He did warn the British."
And this: "In a shout-out, gotcha type of question that was asked of me, I answered candidly. And I know my American history."

I guess a gotcha question is any one ending with a question mark, or asked with a rising inflection at the end.
