From Ben Jones’ Benblog:
I wonder if, the same way we possibly have a residual ancestral memory of snakes eating early hominids that makes certain people fearful of snakes, if the inexplicable fear that some of us have for clowns and realistic dolls and marionettes and that horror of horror a realistic looking clown marionette, which provides so much latitude for interpretation, and hence, ubiquitous, unmitigated terror, is a residual future perception, of a world where clown marionettes eat our progeny.
