Ningen Doubutsuen

I just remembered how relatively extreme these two shorts are, so much so that I am not exactly sure if many can make a lot out of it. In other words, welcome to the dark side of creativity. Both have some sexual undertone to them as well.  

Both are old, short movies with almost no story and hand-drawn like animation. Both are dementia genre, so you will feel like you´re on a drug trip while watching those. Also, both have no dialogue. 

I'd like to believe both are forms of adult humour, but I am not entirely sure. Shitcom is easier to make out with what is going on with its toilet humour compared to the subtle Human Zoo with ideas I am not too sure what one could make out of other than some obscure reality "kinky" reference. 

Both are short videos with no dialogue, both have people transforming to animals/acting like animals and both have hidden message (I think). 

Shigofumi was heavily inspired by concepts first explored in Human Zoo. 

Both are old anime with no dialogue and a bit odd animation
