Oh you poor sheltered dears.
Gentlemen and gentlemen, I give you Quiz Rape Shock, the Japanese edition of Who Wants to be a Millionaire. The female contestant is strapped into the seat at the top of the mini rollercoaster track. At the base of the track is a mob of horny men. The contestant is asked ten questions. If she gets them all right, she wins a million yen. If she gets one wrong, she is sent down the track to be stripped and raped by the mob. Lifelines do exist, but using them can double the size of the mob, arm them with hitachi wand vibrators, or arm them with enemas.
There are seven in the series and one clip compilation, all of which can be seen here:
