Scary clown sightings.... The ONLY thing that keeps this from being nothing more than a rather pathetic cry for attention is that it is preferable to listening to the lickspittles in the mainstream media attempting to hide their bias.
Every couple decades a weird fad of fear/sightings ignites the country. This decade it's scary clowns. In the 90's it was chupacapbra and UFO's, the 70's was satanists, the 50's was UFO's (the first time). I'm sure there's more I'm missing.
