Apparently all the time?
"He who warned, uh, the British that they weren't gonna be takin' away our arms, uh, by ringing those bells, and um, makin' sure as he's riding his horse through town to send those warning shots and bells that we were going to be sure and we were going to be free, and we were going to be armed." --Sarah Palin, on Paul Revere's midnight ride, June 3, 2011
"Because of that one episode, that one episode, that would turn an issue into what it has become over the last two years. I think that's ridiculous. That's one of those things, where that issue...that I don't read, or that I'm not informed, it's one of those questions where I like to turn that around and ask the reporters, 'Why would it be that there is that perception that I don't read?'" --Sarah Palin, ABC interview with Barbara Walters, Dec. 9, 2010
Sarah Palin, on writing
notes on her hand during her Tea Party convention speech: "I didn't really had a good answer, as so often -- is me. But then somebody sent me the other day, Isaiah 49:16, and you need to go home and look it up. Before you look it up, I'll tell you what it says though. It says, hey, if it was good enough for God, scribbling on the palm of his hand, it's good enough for me, for us. He says, in that passage, 'I wrote your name on the palm of my hand to remember you,' and I'm like, 'Okay, I'm in good company.'" (March 5, 2010)
