I honestly read that as Satan's Sphincter the first dozen times I saw it. Which, of course, led me to wonder why anyone would want to see it (the film or the subject). Then, of course, I got to thinking about what might come out of there, which led me to wonder what Satan would eat, how he'd digest it, and so on. So, it was not entirely pleasant.
Then I realized it was Satan's Sphinx, which led me to think of the Sphinx, which is a big cat with a human head on top of it, which led to other ways to say "cat" and then to euphemisms for cat, which led to other unpleasant thoughts regarding Satan and... that.
So, overall, I'm thinking it's best it was banned, because even hearing the title led to a bit of personal hell for me.
