I'm not making this up: This movie, from 1897, was the first ever "adult" film. It is very tame by today's standards. You could show it on tv with no problems. It involved two women, wearing skin colored suits. One of them is in a bath, and the other has a pitcher full of ashes - the ash is supposed to be water, but the water wouldn't show up on the 19th century film. So she pours the ashes over her and washes her. It's about a minute long. Melies advertised this in his film catalogue as ideal for bachelor parties.
