On a recent broadcast of KBS 2TV's "Nocturnal", F.T. Island's Lee Hong Ki revealed his thick leg hair. On this day, Hong Ki wore ripped black jeans, which caught people's attention. Upon seeing his legs, the MCs asked, 'Why are you so hairy? Are you wearing hairy pants?' Hong Ki answered, 'I'm very hairy. I have hair from my legs all the way to my waist. It's all over my front and back.' SHINee's Onew said, 'It's like leggings,' causing the studio to burst out in laughter. However, singer Gil was the only one who didn't laugh. He didn't know what leggings were. Seeing his expression, the MCs started to tease him about his lack of knowledge. The angry Gil retorted, 'I know what leggings are. They're not the same as stockings!', which changed the atmosphere immediately.
