Atlanta-based TBS will air a Conan O'Brien special on Saturday April 9 at 11 p.m. where he recently visited South Korea. "The Walking Dead" star and Korean-American Steven Yeun joins him.

They will visit Seoul and other parts of the country including the Korean Demilitarized Zone between North and South Korea. They put together a K-Pop video.

Yeun has visited Conan in the past and they did a bit at at a Korean spa:

In the last two years, O'Brien has travelled to Armenia, Quatar and Cuba. Over the years, he has also made visits to San Diego for Comic-Con, Chicago, Atlanta, Dallas and his former environs in New York.

Variety magazine said late-night show ratings have suffered across the board with increased competition and Conan himself is down 19 percent year over year among 18 to 49 year olds.
