“Team Coco” recently added Korea to the list of the many places the show has visited. During the trip, Conan O’Brien and The Walking Dead’s Steven Yeun toured the incredibly tense Joint Security Area along the demilitarized zone for some less-than-easy laughs.

At one of the most tense checkpoints in the world, Conan pointed out the odd custom of stoic soldiers wearing really dark sunglasses even in dimly lit conference rooms and noted that the South Korean soldiers were dressed like Janet Jackson backup dancers. So good.
