MC Mong's most recent song, Horror Show was known to be a big flop compared to his past songs. On the recent episode of Strong Heart, MC Mong had talked about the failure of the Halloween-themed song. MC Mong said "I heard that it was because of the featured artists that made my songs big hits. So this time, I had released a new track called Horror Show. This song had featured Kang Ho Dong and after 3 months of convincing, I finally released the track. I thought that this song was going to be a big hit just like Tiger JK and Yoo Jae Suk's collaboration with "Lets Dance" for Infinity Challenge. But it seems like Kang Ho Dong's rap sounded offensive to listeners." He then said with eyes in tears, "The failure of the song is fine. The problem is that Kang Ho Dong made a deal with me that I would have to perform at 20 events for his featuring. I performed Circus infront of a road of moving cars in Busan. My pride is all gone." The embarassed Kang Ho Dong, who is the MC of Strong Heart got on his knees and apologized to him. Then MC Mong quickly ran out and apologized to him as well because he didn't know what to do. Well I don't know if it was because of Kang Ho Dong that Horror Show was a failure, but I thought it was a flop because it sounded so familiar to his past songs.
