At the beginning of the movie, a man stands by the seaside and masturbates. After 5 minutes, the audience will think it's a pornographic film;
As a result, he "spits", and two little animals crawl out. The audience will think it's a science fiction film;
When the camera pulls back, there are fifty thousand men like me masturbating by the sea. The audience will think it's an art film;
Hahaha
