Great show. Known as "Knowing Bros" in S. Korea, it's a classroom setting with grown men as the "student" hosts to grown-up "transfer student" celebrity guests. They play some games and screw around for close to 90 minues.
It's a much appreciated addition to Netflix's impressive and growing Korean language lineup. I've seen many episodes elsewhere online and can tell some minute differences in this Netflix import.
For instance, I HATE that most if not all of the idol music isn't licensed and whenever an act performs, they're dancing to some generic songs from an apparently free bank of stock music. But hey...beggars can't be choosers. At least I don't have to scour the net looking for playable servers....
Come to think of it, it's pretty hilarious to see a popular group performing their guts out to some foolish, cheap club music dub.
