The most hated entity alive

The biggest party in the world will not take place on New Year's Eve. It will take place on the day the clown finally passes away. Society will dance and will know what world peace feels like, if only for a moment. While another entity will eventually take its place, it will always pale in comparison to the clown. The world has never seen such a level of disgust and evil and never will again. Most people didn't realize they could hate something so much until the clown was born. The feelings grew along with the baby.
