Super Junior leader Leeteuk shared a story about how he and Kangin put on a show for their fellow members to encourage discipline.

On the July 23rd episode of MBC's 'Come to Play', Leeteuk explained, "Because Super Junior has a lot of members, we cannot let the team's level of discipline fall. Right before our debut, I was worried about our state of discipline, and so I consulted Kangin."

According to Leeteuk, he and Kangin agreed to set an example for the other members. After calling the Super Junior members to come together, he faced the group and said, "These days, our team's sense of discipline has been falling apart." He added, "It feels like it's the hyungs' fault. Kangin, come forward." According to plan, Kangin came forward and said, "I [agree to get hit]."

Leeteuk continued to reveal, "But then, suddenly, Yesung came forward and said, 'Hyung, I [will also receive the same punishment].' When I asked, 'How many times do you want to hit him?', Yesung replied, 'I will as many times as you do'." Apparently, the situation backfired on them and led the plan astray, causing Kangin a bit of embarrassment.

Leeteuk said, "After thinking about it and coming to the conclusion that once wouldn't be enough, I hit him three times." He concluded, "Later on, I said I was sorry to them both, and told them that if an opportunity arose in the future, they could hit me."
