Comedian and TV host Craig Ferguson has a passion for history, which he shares with his guests on this show. Ferguson debates his guest panelists -- who include fellow entertainers and history experts -- on provocative and timely topics related to history, including the most doomed presidential campaign and history's biggest frenemies. The show's title, "Join or Die," has a double meaning: it was Benjamin Franklin's 1754 rallying cry to the colonists and it's the tattoo Ferguson got on his forearm upon becoming an American citizen in 2008.
