It's hard to pick just one. Maybe the Japanese gameshow where a group of guys had to identify which woman is their mother while she hides behind a wall with only her breasts vulva exposed.
Or pretty much any porn starting with the description Japanese gameshow...
A coworker of mine once messaged me a porn of some dude playing with over-sized buttplugs and his anal prolapse. I thought it was hilarious, so I sent it to a few people that I disliked.
It came from Japan. Japan's game shows, manga, anime, montages, games, etc. I remember their was a montage where this woman was being assaulted by tentacles. The film "Funky Forrest". http://en.m.wikipedia.org/wiki/The_Dream_of_the_Fisherman%27s_Wife
