Dr. Emily Friedman returns to the show. Last time (which was admittedly way too many years ago), she was an expert on the way history smells. Now she's become the premier public scholar on the burgeoning world of table top role playing games. What are her favorite hidden gems - simple enough even kids can play?  And what's going on with D&D these days? Speaking of D&D, Kathy and JR. do a quick review of the new film.
