Calling all grammar fans! We've got the interview for you

Grammarian Ellen Jovin discovered that when she set up a table outside a subway station in New York with a sign encouraging people to ask their grammar questions, it was a huge hit. She and her husband Brandt Johnson took the grammar table on the road across America. The result is Rebel with a Clause, a book written by Jovin and a documentary directed by Johnson. They tell Jesse what they discovered.
