Lim Chang Jung began, "My son asked me why I don't hold concerts anymore. So I called up Psy and found out he was having an end-of-the-year concert. And was asked to perform first so that's how I went on stage."
Hearing this, Kim Chang Ryul commented, "I am kind of bitter about that. You sang only two songs at our concert, but sang like three songs at Psy's."
To which, Lim Chang Jung explained, "There were a lot more people at Psy's concert. He's more popular too," causing much laughter.
