Pretty soon, nowhere in the United States will be safe from creepy clowns, or creepy clown hoaxes, depending on whether you're a believer or a skeptic.
The latest cities checking in with clown hysteria are Dallas, where the Dallas Morning News reports that four high schools ramped up security after clown-related threats popped up on social media, and Philadelphia, where NBC 10 reports that authorities are taking clown threats against schools seriously.
Many of the nationwide clown threats have been proven to be hoaxes.
A few of the cases have involved people actually dressed up as clowns chasing people.
The majority of the clown hysteria, though, is unexplained, and nearly impossible to prove, like this woman's story from Fort Worth, Tex., where she says she encountered creepy clowns peering into cars in a Target parking lot.
