Welcome to a new segment in 15-Minute History called, Pop Quiz! Every other Thursday, Joe asks a topical question about history, and Jon has to answer it without any help or resources - other than his legendary memory and knowledge of history. These episodes are unedited and a fun way for the team to interact more with you, our outstanding audience.

Have an idea for a topic? Want to try and stump Jon? Send it to us at [email protected] or submit it to our website at https://www.15minutehistorypodcast.org. We promise not to give him any hints.
