On this episode, we explore the cold hard facts about Brain Freeze.  One minute you're enjoying your favorite ice cream, and the next feels like a railroad spike is being driven into your skull.  We'll tell you why it happens and how best to avoid it, also the custom of clapping.  There were once other ways to show appreciation, but somehow smacking your hands together won out.  Plus, what's the origin of the phrase "feeling under the weather"? What does calling in sick have to do with the seven-day forecast?  Get all the curious details as host Rick Peterson answers more of the questions you've Always Wondered about.
