On this day, as the members were sitting around the fire after being soaked in the water, Dongwoo suddenly pulled down his pants and squatted right on top of the dying fire in order to dry his wet underwear in front of the camera. 

Surprised and taken aback by his actions, one comedian cast member commented, "Dongwoo's fans are going to double," while others jokingly added that his career would be ruined once he shows his front to the camera.
