While guesting on the latest episode of SBS's 'Running Man', the 'godfather of variety' Lee Kyung Kyu had a discussion about his reputation of being hard to deal with on the set, with his team members bringing up the fact that the scriptwriters used to tremble in fear when they bumped into him in the hallways.

However, Yoo Jae Suk said that he had never had that experience. "For some odd reason, Kyung Kyu hyungnim has always treated me well," he added, with not a small amount of pride. Lee Kyung Kyu himself agreed, but with a caveat. "Of course, there are a couple people I don't like," he said.

When pressed for their names, he didn't directly respond. However, he said offhandedly a few seconds later, "Is Park Myung Soo doing well?", cracking up everyone in the car and leaving no doubt as to who Lee Kyung Kyu considered to be a 'bad' junior.

"Although he likes to talk with his juniors, he really hates talking without a purpose and talking that isn't funny," Yoo Jae Suk pointed out.
