S. Korean President Yoon pulled out an unexpected performance of 'American Pie' at the White House State Dinner. Was it a cringe moment? Or did he actually prove his street cred and boost the image of Koreans? In any event, he reminded us that many careers in Korea are built on how well you step up to the mic to impress your colleagues and keep your haters at bay! While promoting Korea's soft power, Yoon showed that he could also bring it to the stage. Now it's Biden's turn to sing some K-pop.
