Extra-large underwear? Sure we have some! Let's see, large, large, EXTRA-LARGE! Here thye are! Great big, extra-large UNDERWEAR!
This was another book with some jokes that seemed squarely aimed at the adults reading, though some kids certainly got most of the humor, depending on their knowledge of American history (and of the Beatles). Also, the book certainly takes liberties with characters and history (that was Paul Revere selling underwear in his shop as opposed to silver), but it's not as if I was reading this as a primer on the Revolutionary War. In fact, the true/false questions at the end actually did lead into real history talk... and everyone seemed to have fun with it. That seems good to me. Then again, I'm just a volunteer librarian... and a guy who enjoyed saying the above passage with all library doors open.
