Last week I posted the Mark II Grande with MC Hammer pants (aka harem pants) and on facebook Brad Hogan commented with a link to this video of the LL Brothers:
The LL Brothers was a TV show duo in the early 90s consisting of Takanori (older brother) and Masaya (younger brother) performing synchronous dance like shown in the video above.
They did immitate a lot of popular US rappers, like for instance MC Hammer or Will Smith as show in this video:
Observe their TV Intro:
Apparently they were very popular back then and they somehow managed to convince someone to create three (!) films! Insane! :D
