Characters I find very funny:
1) Wai Siubo- for obvious reasons
2) Mao 18 - whenever he's paired up with WSB
3) Zhou Qi - from "Book & Sword"
4) Zhou Botong - especially his conversations with GJ on the island about "9Yin"
5) Taoist Mu Sang - the "chess-player" who taught Yuen Cheng Zhi in SSRB
6) Shi Potian in "Xia Ke Xing" - this guy is like the Super-Saiya Man but totally clueless
7) Tao Gu 6 Xian, Tian Bo Guang, Bu Jie Monk - from "Xiao Ao Jiang Hu"
