J.Y. Park, the founder of JYP Entertainment, appeared on MBC Everyone's 'Weekly Idol' on April 20, which caused the show to demand for the appearances of the founders of SM and YG as well.

On this day, J.Y. Park looked at the set and said, "I was very surprised.  I thought it was a waiting room.  But when it came time to do to the show, they quickly cleaned it up.  This time, this is my only variety show.  I had either appeared on all the others already or there's a format, so I can't do it comfortably.  This was the only one I wanted to come out on."

Hearing this, Heechul threw in, "There's 'Real Men,'" and Defconn jumped on board with, "There's also '1 Night, 2 Days' and 'Running Man.'"

Defconn continued, "We had just thrown the question at J.Y. Park to cast him for an appearance, but he said he would, so the production crew was taken aback."  Heechul then said, "If that's how they come out, then next, let's call for Lee Soo Man," making J.Y. Park clap and laugh.  Defconn added, "Yang Hyun Suk has to come out, too," then said to J.Y. Park, "Thank you for willingly coming on board."

Better yet, can we get all three on at the same time?
