I think kids don't like clowns because people read others with body language and facial expressions. With all of the makeup, you can't read a clown. It's disturbing to have a person smile with a frown painted on. A lot of the newer clowns don't use the makeup. They have a funny nose and clothes, but no other human-altering makeup.
Oh, and my son like the
Insain Clown Posse which REALLY frightens me!
