On the July 7th broadcast of KBS 2TV's "Invincible Youth 2", Jo Kwon(2AM), Lee Joon(MBLAQ), and Kwang Hee(ZE:A) participated along with the G6 members and personally harvested vegetables and used them to cook. 

On the day prior to harvesting crops, the members played games such as watermelon spitting and watermelon eating race in order to split the teams. Suzy, Sunny, and Jo Kwon became a one team.

As these three members held each others arms up to shout "fighting," Jo Kwon grabbed Suzy's wrist and noticed a watermelon seed stuck.....only it was a mole. Instantly, the set was filled with laughter.

Although the G6 members and the fans knew of Suzy's mole, Jo Kwon did not and continued by saying "I really thought it was a watermelon seed" embarrassing Suzy even more.
