1197. This week, guest host Valerie Fridland steps in for Mignon and talks to Jess Zafarris and Shannon Miller about their new book, "A Miscellany of Weird and Wonderful Facts for Curious Humans." They look at fossil words, eponyms, and the surprising origin of the word "electric." They also look at mountweazels, the medieval roots of modern romance, and why emoji has nothing to do with emotion.
