Dahyun and Jooheon failed, and Jackson tried the challenge. But when he failed the handstand because of his thick shoes, Jackson yelled, "Ah, shinbal (shoes)!" alarming the MCs because the word for shoes sounded like a Korean curse word (shibal). They thought that he had said a terrible word, but Jackson was quick to explain that he was yelling at his shoes, making everyone laugh.
