February is Black History Month, and comedian Baratunde Thurston wants you to know that it’s the perfect time to buy his new book, “How to Be Black.” “The odds are high that you acquired this book during the nationally sanctioned season for purchasing black cultural objects, also known as Black History Month,” he writes. “If you’re like most people, you buy one piece of black culture per year during this month, and I’m banking on this book jumping out at you from the bookshelf or screen.” Baratunde Thurston joins Celeste Headlee to discuss his new book: part-memoir, part-satire, part-political commentary. Baratunde Thurston is the author of “How to Be Black” and the digital director of The Onion.
