The whole thing is that there is no point or purpose. It's a bunch of naked men walking down the street singing. I thought that was pretty clear that it was just a random and funny short film, I don't get why you're all asking for some sort of deeper meaning behind it
Well when you refer to it as being "beautiful" and "one of the best short films you'll ever see," I just kind of presume that there's some sort of message to it
