Its just like humanity to always blame their experience on someone else....
Personally, I have never understood the appeal of the "clown". I love to laugh but dressing up as a clown is a little "over the top" for me.
My kids were always afraid of clowns. It didn't have anything to do with IT. The creepy/evil "IT" clown pretty much is the reality of what people perceive to have always been there underneath.
