The video shows them stripping off white bathrobes and getting into a hot tub and glancing at fellow male guests, who are also depicted as nude.
"Hello," O'Brien says, waving awkwardly. "You're naked."
The two also hung out in a sauna with three seemingly nude men and it's just awkward moment after awkward moment.
Yeun speaks a little Korean to one of the men, who doesn't appear to exercise proper etiquette regarding personal space...as well as a couple of other things.
O'Brien, still appearing naked, also receives a body scrub—including in a very sensitive place—from a man while lying on his back and voices his extreme dissatisfaction, while Yeun, who had warned him that it "sucks," completely loses it. Of course, then it's quid pro quo.
The two also make conversation with a woman in a 213-degree clay sauna, during which she lists her favorite TV shows, which does NOT include The Walking Dead, or Conan, for that matter.
"Thanks for joining me," Yeun tells O'Brien after their day at the spa. "This was fun."
"No, no that was not fun," the host replies.
"I had a blast," Yeun says.
