Host: So you guys do fight, right?
Leeteuk: Yes, we actually fight
Heechul: There was once when we actually fought seriously, but we don’t fight that often. If that happens, now that’s going to be a big problem, because if the two of us fight, the two main pillars of Super Junior get shaky… and actually, none of our dongsaengs can stop us.
