Coulrophobia | coul·ro·pho·bi·a [kool-ruh-foh-bee-uh]
noun
an abnormal fear of clowns.

I developed a severe case of coulrophobia when my friend's dad thought it would be a good idea to let us watch Stephen King's "It" featuring Tim Curry as the evil clown Pennywise.  I still get chills whenever the circus comes to town.  Even Ronald McDonald freaks me out.

Needless to say, I was afraid of clowns before I saw this, and this video didn't make it any better.  Watch as this prankster scared the living (insert expletive here) out of people while dressed as a clown wielding a giant sledgehammer.
