While clowns in general don't frighten me, I can definately see where they could. And I'll admit that Stephen King one did rattle me too! Your grocery store experience did remind me though that I was absolutely terrified of the Jolly Green Giant as a kid. Those big cut outs of him that they used to have in the grocery stores way back when, used to scare me silly. I would start screaming and crying everytime I saw one, don't know how my mom ever got any shopping done with me in tow.
