I have a few phobias. Don't like spiders, centipedes, and I don't particularly dig being in closed in spaces where escape could be difficult,i.e. the back seats of two door cars. So I do understand the clown thing. Especially since the John Wayne Gacy horror story. Clowns are creepy because they are masked, and they are usually adults acting like little children, both of which are weird and unsettling. Like most spiders, they are harmless. And so it goes...
