I'm currently working on an essay all about Picha's superb cult classic Shame of the Jungle (1975) and have come across a whole host of 1970s dirty animation. Cartoons that blur the lines between pornography and comedy. But here's possibly one of the first to start it. Not much is known about this film, except that it was probably made around 1924/25 by a couple of cartoon studios at the time, out of hours - most likely the Fleisher studio. Thought to have been made for stag parties this is quite possibly one of the strangest and freakiest animations you will ever see!

For everything strange and odd in the world. Mysteries, the paranormal, the unexplained, horror films/games/books. In short, all the freaky stuff.
