What's weird about US Presidents? Plenty. Some more than others, of course.
Martin Van Buren helped popularize the phrase OK. His nickname was Old Kinderhook and so his crowds of supporters would chant OK and eventually it became known to mean all correct.
Back when Zachary Taylor was President the receiver paid the postage and since Taylor didn't like spending money, he didn't always pick up his mail. He didn't find out that he was nominated President until a month after it happened.
As you can see, it's not necessarily "weird" facts, but little-known facts. I enjoyed reading the book and will keep it on our American History shelf. There is a 2-4 page spread on each President except Obama who gets six (He has read all the Harry Potter books aloud to his daughters!) and Trump who got one (detailing how he got his money from his Dad, lost it and earned it back).
This book is image heavy with lots of blurbs and sidebars, it makes it difficult to read through in one sitting, but I think would work well on your shelf to pull down and read alongside your American History study one President at a time.
