Leeteuk and Heechul once got into a big fist fight?

 
The MCs asked the two members to detail exactly how the two ended up getting into a physical fight, and the two started off by declaring, "We had a huge fight." Leeteuk explained, "I always tell Heechul that he's a great friend, but work-wise, he's really mediocre. One time in Incheon, we fought for about 30 minutes right before we got on stage," pulling the incident from the depths of his memory. 

Kyuhyunchimed in, "Leeteuk started the fight first. Heechul swung his fist at him, but I ended up getting hit instead. I couldn't even say that it hurt because the situation was so serious; I just suffered the pain without a word," making the studio ring with awkward laughter. 

MC Kim Gu Rapointed out that Leeteuk told Heechul to "get lost" when Heechul attempted to reconcile with him back at their dormitory. As it turns out, the two are very different in how they try to resolve a conflict. The leader needs a bit of time to cool off from an argument, whereas Heechul is the confrontational type who has to talk it out right then and there. 

Whatever the cause for the fight was, it must have been a serious one as Leeteuk told the hosts, "We didn't talk for three months."
