On December 22 episode of SBS 'My Little Old Boy', KyuHyun made a guest appearance.

KyuHyun said, "There are so many crazy guys within Super Junior. Before I joined the group, I thought I was a bit unusual. It turned out that I was normal though. That is how seriously insane Super Junior members are."

He added, "At one point, we sat around and rated our craziness. We concluded that LeeTeuk SiWon, YeSung were the top three craziest ones out of us."
Then, Seo Jang Hoon curiously asked, "What about HeeChul? He's pretty crazy, isn't he?"
KyuHyun laughed and responded, "Actually, HeeChul is a normal person who pretends like he is crazy."
