Well known singer and g.o.d member, Kim Tae Woo, showed off his superior acting skills in order to trick MBLAQ member Lee Joon. Although Lee Joon attempted to plan a prank as revenge during an August 6th episode of KBS's Invincible Youth, it turned out that he was the one who was being pranked. The prank Lee Joon performed involved pretending that he had various allergies, so he would lie on the ground almost acting like he was passed out. Lee Joon believed that he was tricking Kim Tae Woo the whole time, so he told Kim Tae Woo that everything was all a prank towards the end. After Lee Joon told this to Kim Tae Woo, the hidden prank that Kim Tae Woo planned for Lee Joon officially began. Kim Tae Woo posed a question to Lee Joon and asked him a question as if he was seriously worried, "Why do you do that to one's body? I was totally surprised!" The older singer then pretended to get angry towards the MBLAQ members, as he asked if they all knew this was a prank. He then gave the idols a serious lecture about how they shouldn't pull pranks on singers who are much more older than them. Lee Joon, who was really upset and ashamed over performing the prank, crouched down and put his head down, as he was visibly upset. At this moment, Kim Tae Woo surprised Lee Joon and told him that this was all a prank, relieving the idol and putting a big smile on his face.
