Asians acting like fools during karaoke is an internet mainstay. For some reason, schoolgirls, fey dudes who love Mariah Carey (both from Korea), or Chinese Backstreet Boys pretty much take the cake in this department.
I guess it’s the William Hung-ification of bad singing and weird dance techniques, but I find this following clip from Japan pretty hilarious. Japanese comedians are truly a unique bunch. This duo is known as Tetsu and Tomo. They are an owarai duo, and Japan has a rich comedy tradition. It’s broad and slapsticky but… sooo Japanese.
