ALOT OF WHACKING GOING ON

So i was up watching japanese tv, they dont quite got the reality tv shows going yet, but they make it up with some crazy ass shit. So from what i could understand from this show is that these 4 popular comedians go back to school, high school that is. And its like a boot camp. If they even "laugh" someone calls out their name and they gotta bend over while a masked guy in a blue suit rolls by and whacks em in the ass with a big ass kendo stick! Shit! So they go throughout the day at school while wierd shit pops up like a belly dancer and they try not to laugh, but seems like they cant control themselves. So whack, whack, whack it went ... funny shit ...
