O'Brien recently caused quite a stir when he arrived in Seoul, South Korea, to the cheers of thousands of screaming fans. That festive welcome kicked off a weeklong trip in which he was joined by Korean-American actor and The Walking Dead star Steven Yuen. The two explored various parts of the country, including the Korean Demilitarized Zone (DMZ) and the Joint Security Area (JSA). O'Brien and Yuen also teamed up with music sensation J.Y. Park to film a K-Pop music video.

Guests: Aaron Paul, John Bradley, Ben Rector.
