Clowns are creepy, I think most of agree on that. Some people are so creeped out by clowns that they fall apart in the presence of a clown. That is called coulrophobia, and it can be treated. It seems that it would be easier to just avoid clown.
Dr. Dena Rabinowitz explains some the reasons that we instinctively do not like clowns, and they make perfect sense. That touch od weirdness is great for pop culture horror stories. But if you are seriously coulrophobic, you'd be better off not going to see It in theaters, and just skip this year's American Horror Story on TV. -via Digg
