On the KBS night variety show Nocturnal Habits, Super Junior's Heechul, Shiwon, Shindong, Ryeowook, Donghae, and Yesung made guest appearances. Super Junior members all agree that Yesung is an avid video collector and he has, "A collection of every kinds of videos." MC Shin Dong Yeob asked the members, "What do you guys usually during this time (night)?," and to make matters more curious, Heechul slyly didn't give a full answer and replied, "Can't reveal on broadcast." Yesung gave a full answer and said, "I like to watch movies." Starting with witty Heechul and later expanding to the Super Junior members and the MCs, they started to lead Yesung's response towards 'porn videos.' Shindong added, "Yesung has a broad collection of soccer, baseball, and porn videos," which sparked a lot of laughter. Whether the latter genre is true or not, this will always be a confidential information that only the Super Junior members would know.
