Clowns, by definition, are supposed to make you laugh, but in the background is the fear that they won’t, and all of us have that in the back of our mind: the fear that you won’t actually be able to do the very thing that you’re designed to do.
when clowns dont do the things they are designed to do. (make laugh, jest at society) unnatural smiles. smiles are usually registered in the brain as good things but when the smile is "all the time" something is not right. with clowns facial expressions help to show somebodies intent, and the way they behave, but when there is no change to the facial expressions it sends shivers down the audiences spine.
