Haha (born Ha Dong Hoon (Korean: 하동훈, Hanja: 河東勳) on August 20, 1979) is a South Korean entertainer. He first debuted in 2001 with a hip hop group named Jikiri, although the group was not very popular. His fame grew when he began to imitate Kim Jong Kook on the popular variety show X-Man, on which he became a series regular until its end in early 2007. He was also a host of Manwon Happiness (also known as Happy Shares Company). Many jokes are made about his short height, similar to MC Mong being made fun of for resembling a monkey.
