A large percentage of the Asian population takes pride in staying at the office later than everyone else, so it's not exactly a surprise that some of these people aren't satisfied with your run-of-the-mill blurred pornography.

They want competition.

Obscure game shows (and adult movies masquerading as ones in order to convince the Internet Asia is weirder than it actually is) have always loved combining sexual humiliation and the spirit of competition, like this show that combines karaoke and hand stuff.

This late night show features a lot less of the former but a lot more of the latter as two guys see who can be the first to make it to the finish line (with help from scantily clad assistants) while presumably trying to avoid making eye contact.
