As a kid, you may have played that game where you phone someone to say, “Is your refrigerator running? Then you better go catch it!” What’s the term for that kind of practical joke? Is it a crank call or a prank call? There’s a difference. • If someone has a chip on his shoulder, he’s spoiling for a fight — but what kind of chip are we talking about? Potato? Poker? Hint: the phrase arose at a time when working with wood was more likely. • A conversation with an expert on polar bears leads to a discussion of history and folklore around the world. • Plus noon of night, omadhaun, chicken lights, choke-and-slide, tragomaschalia, another think coming vs. another thing coming, and bada bing, bada boom.  Read full show notes, hear hundreds of free episodes, send your thoughts and questions, and learn more on the A Way with Words website: https://waywordradio.org/.
