If you find yourself walking down a tree-lined side street of any big city, you can be sure that eventually you'll find a book. It's in a box of other books, put out on the steps of a brownstone. Or it's on the road by the curb, having jumped out of a car, unnoticed by a busy driver. It could be moldy and weather-worn from propping up an A/C unit all summer, or new and plastic-wrapped, sold to you for $5 by a guy who has a brand-new theory of relativity that will put Einstein to shame if only enough people would read it.Found books are the flotsam of urban life. When we encounter them we can't help but wonder who had them and why. And how did they end up on this street or under this park bench?Hotsource is a comedy podcast about found books. Every episode, Gabe Silva and David Rabig, two old friends, select a book about which they know nothing, they read an excerpt, and use the resulting conversation in a short improvised scene. It's like you found a book on the street on the way up to meet a fast and funny friend at a bar. The two of you peruse, write conjectures and jokes, and end up drinking more and staying later than either of you intended. This is the Hotsource podcast.Welcome, friend.
