The November 23 airing of 'Healing Camp' had viewers chortling thanks to Yoo Hee Yeol's sassy, brutally honest remarks about his 'K-Pop Star' fellow judge J.Y. Park. 

Yoo Hee Yeol, along with Yang Hyun Suk, guested on this episode to air out some dirty laundry about their friend J.Y. Park, who apparently has some weird mannerisms and habits that grind their gears. Yang Hyun Suk said, "There are times when the viewers get annoyed watching J.Y. Park on the show. When they just look at his face, they know whether a contestant is going to pass or be eliminated," which had Yoo Hee Yeol laughing in agreement. He then added his own two cents, saying, "If there is a contestant he even likes a little bit, he starts making moaning noises. It's very uncomfortable."

Yoo Hee Yeol continued, "There was a famous line that [J.Y. Park] said on the show that went 'half air half noise' but nowadays he says, 'open your diaphragm' and 'your heart is also a muscle.' I have no idea what he means; it's not like he's a doctor." 

But wait! His dissing didn't end there. When asked what he would do if J.Y. Park was one of the contestants, Yoo Hee Yeol joked, "I think I will eliminate him based on his physical appearance. I would assume that he's trying out to be a dancer." Hey, you gotta appreciate the guy's honesty. That's what friends are for, right?
