TVXQ appeared on the February 8th episode of SBS's "Strong Heart", and Yunho made a hilarious confession about his stage height insecurities. Yunho and Changmin are known for their towering physique, but in Yunho's eyes, it's difficult to accept that Changmin stands two centimetres taller. He expressed, "I feel pressured when I stand next to Changmin because he's so tall and handsome... that's why I place thin sponges in my shoes." Changmin caused the studio to crack up when he teased, "They're not even thin. He's always floating in the air." Still, MC Kang Ho Dong couldn't retain his shock, as he mused, "I never would've thought that Yunho used sponges." Slightly irritated by the teasing, Yunho blurted out, "Changmin wears them occasionally as well!" Source + photos: Nate
