I recall seeing a movie at a friends house several years ago back when I was in my teens! Can not for the life of me remember it all that much, and I'm racking my brain trying to think of what it was called! It was sort of a comedy sex film, but very old. There are 3 main scenes I vaguely remember from it.

Scene 1: (right at the start I'm fairly sure) Is some teacher confiscates a students "apple juice" (he pee'd in it for some reason, I don't remember!) and then she drinks it and shivers.

Scene 2: A HUGE orgy from memory. Pretty much a pile of people laying on top of each other whilst 2 males watched from outside.

3rd scene: I think it was some sort of science experiment to get some guy turned on, where they basically put toothpicks to keep his eyes open while some nurse did a strip tease for him. He then gets out of the chair to some room with a really oiled up lady and jumps on her, only to slide out (from all the oil) and ends up sliding into another room with an ugly maid.. or something? Not sure!

Few other scenes here and there jump to mind, one of a platter of food with a naked lady sitting in it.. another scene of a wedding (I think)

Sorry for not much info, but that is literally all I can remember! PLEASE HELP!

Thanks in advance.
