I can think of is the first unscrambled porn I ever saw, called memorably Juranal Park, which had a horrendous and hilarious sex scene where a woman with a very nasal and pronouced Brooklyn accent kept trying to seductively murmur "Ohhh, your balls are slapping my ass, your balls are slapping my ass!" Appearently the director thought that was a selling point. The only other scene I can remember isthe one where, to simulate dinosaurs attacking a building, someone held plastic toy dinosaurs up really close to the camera while wiggling them up and down and making rawrrrr! noises.

Which leads me to conclude that all the best porn comes from the back rooms of tourist shops on the Canadian side of Niagara Falls.
