Yeah, it's a joke. The school they're at is Nexus in Coburg, Melbourne, Australia. Murat Karadenizli, a Pedro Sauer BB, is the head instructor (not in OP's vid). They're a very legit competition school. The brown belt with the shaved head is Kit Dale, a Peter de Been student who does pretty well in competition.
I think my brother took lessons from him.
He already looked familiar, I think I saw this guy on the photo with my brother when he was training there during his time in Oz.
I'll ask him soon.
