When it comes to trying new things, Conan O’Brien is fearless. He’s been a Texas Deputy, a Mary Kay Beauty Consultant, a Taco Bell taster, and last night, he got naked. The Walking Dead’s Steven Yeun accompanied Conan on a trip to an authentic Korean spa. Their interactions with mostly older male patrons is so awkward, yet so entertaining. The best part is when Conan receives a full body scrub from Mr. Lee. As Conan writhes in pain, he screams, “What did Mrs. Lee do to you last night?” Watch the full video below for more naked Conan.
