This week on Unorthodox: Scottish Jews get their own official tartan.
Our Jewish guest is L. Jon Wertheim, executive editor of Sports Illustrated and the author, with Sam Sommers, of the new book This is Your Brain on Sports: The Science of Underdogs, the Value of Rivalry, and What We Can Learn From the T-Shirt Cannon. He tells us about the time former Mets outfielder Mookie Wilson called his son to congratulate him on his bar mitzvah, what he thinks the least-Jewish sports are, and what the L. in his name stands for.
