Super Junior's Leeteuk revealed he has new rules for s to follow.

The group recently made their first comeback in 2 years with their album 'PLAY', and leader Leeteuk set down some ground rules. On the November 8th installment of 'Weekly Idol', hosts Defconn and Jung Hyung Don asked Leeteuk, "Doesn't it feel different this comeback as the leader?"

Leeteuk responded, "We've been together for 13 years. I didn't know we'd be together for this long, but I'm happy that we are." He then added, "We made a rule to avoid making showy posts on social media. The punishment is leaving the group. Then Heechul broke the rules, so we revealed a video of him getting spanked on the 3 times instead of making him leave the group."

When he was asked to make a rule for the 'Weekly Idol' filming, the Super Junior leader concluded, "Every time you're not funny, you'll get spanked once."

Remember Heechul getting spanked?
