I believed that when the "Test of the Emenrgency Broadcast System" (complete with high pitcehd soud) came on the TV during cartoons, that they were scanning for emergencies like Russian attacks, tornados and other natural disasters.
I waited anxiously until they announced that this had only been a test to be assured that no disaster was eminent.
