Pranks, cranks, and chips. 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 big difference. Also, 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 there were many more wooden structures around. Finally, a conversation with an expert on polar bears leads to a discussion of history and folklore around the world.
