On the June 23rd installment of 'Knowing Brothers', HaHa claimed he was Seo Jang Hoon's 'variety show' teacher, saying, "Before his debut in the entertainment world, I had him saved as 'MC Seo' even when he was a basketball player. He came from my own stomach."
Seo Jang Hoon responded, "It's true HaHa was a big help. Still, my teachers were Kim Gu Ra, Kang Ho Dong, and Yoo Jae Suk. There are a lot."
Do you see HaHa's influence in Seo Jang Hoon's variety show comedy?
