This weekend's NATO Summit in Chicago is expected to be fraught with protesters. But authorities said they're keeping a keen eye open for a group of clowns who have vowed to take their pies and protests to the streets.

On its website, one member of the The ClownBloq said the group "is both a joke and NOT a joke."

Police agree, with sources telling WBBM-TV that the group is one of the more radical protest organizations, who peel away layers of clown clothing during protests to avoid detection.

The group says its main goal is "To provide hilarity in the face of a humorless police state and to provide a fool’s critique of organized and militarized repression of the people, their voices and their best interests."

According to the TV station, the group also provides its members with basic training in clowning.
